The Server Threw An Exception From Visual Studio .Net 2003

Tue, 10 Nov 2009 14:12:23 -0800

Symptom:
An error message "The server threw an exception" is given when debugging after installing the Intel® Visual Fortran Compiler for Windows* 9.1.034 integrations into Visual Studio* .Net 2003.

This error message can also occur after uninstalling the 11.0 compiler and attempting to use the 10.1 compiler integration into Visual Studio* .Net 2003. It is not an issue when uninstalling the 11.1 compiler.

Cause:
There is an installation-related problem with Intel Visual Fortran Compiler for Windows 9.1.034 when combined with Visual Studio.Net 2003 (only) which results in the error, "The server threw an exception" when you debug after installing the 9.1.034 integrations into Visual Studio .Net 2003.

There is a problem with uninstalling the 11.0 compiler which causes Visual Studio .Net 2003 (only) to be unable to debug applications.

Solution:
The error can be resolved as follows:

Uninstall the Intel Visual Fortran Compiler for Windows* Microsoft integration component using "Add/Remove Programs".

Run a reinstall/repair of Visual Studio .Net 2003.

Re-install the Intel Visual Fortran Compiler for Windows integration component.

This problem will be fixed in the next update, 9.1.036, and does not affect users of Visual Studio .Net 2002 and Visual Studio 2005.

The problem with the Intel Visual Fortran Compiler for Windows 11.0 uninstall is not an issue in Intel Visual Fortran Compiler for Windows 11.1. This problem does not affect users of Visual Studio 2005 or Visual Studio 2008.

IDE integration missing when installing the 10.x release over an 11.x release

Mon, 09 Nov 2009 08:09:16 -0800

Reference Number : DPD200138896

Version : 10.x

Product : Intel(R) Visual Fortran for Windows

Operating System : Windows*

Problem Description :
In some cases uninstalling the 11.x compiler and then installing a 10.x compiler, will appear to still show the 11.1 integration (and not show the 10.x integration) in Microsoft* Visual Studio. If this happens, please remove/rename the 11.x directory and install the 10.x compiler. This directory is in the default location of:

C:\Program Files\Intel\Compiler\11.1\xxx

where xxx is the minor version of the release. This problem will not occur with compilers 11.1.051 or later, although the if older releases were installed at one time you may encounter the problem with an unstall of 11.1.051.

Resolution Status :
Fixed in release 11.1.051 or later.

Intel® Visual Fortran Compiler Documentation not available from Help menu in Visual Studio 2008 Shell*

Wed, 04 Nov 2009 12:12:25 -0800

Reference Number : DPD200137640

Version : 11.1

Operating System : Windows

Problem Description : When using Intel® Visual Fortran with Microsoft Visual Studio 2008 Shell*, the compiler documentation is not available from the help menu. There is a menu option, Help > Intel Visual Fortran Compiler Pro > Intel Visual Fortran Compiler Help which opens the Microsoft Document Explorer but there is no Intel® Visual Fortran Compiler documentation displayed.

Resolution Status : This is a known issue that has been resolved in 11.1 Update 3 (w_cprof_p_11.1.051). This issue occurs when Intel Visual Fortran with Visual Studio 2008 Shell (11.1 versions 11.1.048 or earlier) is installed on a system that has had Visual Studio 2005 Premier Partner Edition (VSPPE) previously installed. To resolve this, simply install 11.1 Update 3. Uninstall of the earlier 11.1 compiler is not required.

Internal Compiler Error When Using IMSL Modules IMSL_LIBRARIES or LINEAR_OPERATORS for Intel 64

Fri, 30 Oct 2009 13:21:40 -0700

Reference Number : DPD200138749

Version : 11.1

Product : Intel® Visual Fortran Compiler Professional Edition with IMSL*

Operating System : Windows

Problem Description : Compiling a Fortran application that has a USE of the IMSL modules IMSL_LIBRARIES or LINEAR_OPERATORS fails with an internal compiler error when building for the Intel® 64 platform. The problem is caused by corrupted compiled module (.mod) files.

Resolution Status : This problem will be corrected in a future version of the product. It can be corrected on a developer's system by unpacking the attached ZIP file into the folder C:\Program Files\VNI\imsl\fnl600\Intel64\include , being sure to preserve folder names. (If you have installed IMSL into a different path, adjust the above path accordingly.) This replaces the defective .mod files with corrected versions.

Incorrect padding added for SEQUENCE or BIND(C) type with UNION

Fri, 16 Oct 2009 12:19:30 -0700

Reference Number : DPD200138527

Version : 11.1

Product : Intel® Fortran Compiler

Operating System : All

Problem Description : If a derived type is declared containing a UNION, and the type is a SEQUENCE type or is interoperable (BIND(C)), and the UNION contains a misaligned field, the compiler incorrectly adds padding bytes before each misaligned field.

UNION is an extension to the Fortran standard, supported by Intel Fortran, that allows the declaration of overlapping sets of derived type components. A SEQUENCE type is a derived type containing the SEQUENCE keyword. The Fortran standard specifies that components of a SEQUENCE type may not be rearranged by the compiler; in Intel Fortran, SEQUENCE types do not, by default, have alignment padding added before misaligned components. (This can be overridden with the "align sequence" option.) Lastly, an interoperable derived type, declared with the BIND(C) specifier, is required to have its components laid out exactly as the companion C processor would do it - this may involve padding if the C processor would pad by default.

Consider the following declaration:

type :: mytype
  sequence
  integer(2) f1
  union
   map
     integer(2) xa1
     integer(4) xa2
     integer(2) xa3
     integer(4) xa4
   end map
   map
     integer(4) xb1
     integer(2) xb2
     integer(4) xb3
     integer(2) xb4
   end map
  end union
end type mytype

Because the first component, f1, is two bytes long, the UNION starts at offset 2. (Remember that SEQUENCE disables padding in Intel Fortran.) This would make components xa1 and xb1 begin at offset 2, causing xb1 to be misaligned, since 2 is not an integral multiple of its size, 4. Components xa2 and xa3 are naturally aligned and should begin at offsets 4 and 8. xb2 is misaligned at offset 6.

Because of a defect, the compiler incorrectly inserts padding before each misaligned variable inside the UNION. The following table shows the offsets for each component, with and without the defect:

Component	With Defect	Correct
f1	0	0
xa1	4	2
xa2	8	4
xa3	12	8
xa4	16	10
xb1	4	2
xb2	8	6
xb3	12	8
xb4	16	12
f2	20	14

Note that f2 is (correctly) misaligned in both cases, and that xb4 received an additional two bytes of padding - the inappropriate padding happens only within the UNION.

Resolution Status : This error will be corrected in a future compiler update. As a workaround, enclose the TYPE declaration in the following directives:

!DEC$ OPTIONS /NOALIGN /NOWARN
... TYPE goes here
!DEC$ END OPTIONS

You can also compile with the "noalign" compiler option.

Run-Time Error 408 when optional character argument omitted

Mon, 05 Oct 2009 13:24:37 -0700

Reference Number : DPD200140203

Version : 11.1

Operating System : All

Problem Description : The following program has a routine "wrapper" that accepts an optional character argument "s" where "s" is declared with a fixed length. It then passes "s" to a second routine where the argument is also declared as optional. The main program calls "wrapper" with the argument omitted.

program omitted

call wrapper

contains

subroutine wrapper (s)
character(10), optional :: s

call doit (s)
end subroutine wrapper

subroutine doit (s)
character(10), optional :: s

if (present(s)) then
  print *, s
else
  print *, 'S not passed'
end if
end subroutine doit
end program omitted

When the program is compiled with bounds checking enabled (/check:bounds on Windows*, -check bounds on Linux* and Mac OS*), the program gets an inappropriate run-time error similar to the following:

forrtl: severe (408): fort: (18): Dummy character variable 'S' has length 10 which is greater then actual variable length 0

Resolution Status : This issue will be resolved in a future update to the Intel Fortran compiler. A workaround is to declare the dummy argument in the "wrapper" routine as CHARACTER(*) rather than with a fixed length. This is a preferred coding style as using a fixed length can lead to unexpected run-time behavior if the actual argument is too small.

Catastrophic error: could not open source file "gmmintrin.h"

Fri, 25 Sep 2009 09:13:49 -0700

Reference Number : DPD200140118

Version : 11.1

- Intel C++ and Fortran Compiler for Linux* 11.1
- Intel C++ and Fortran Compiler for Mac OS* X 11.1
- Intel C++ and Visual Fortran Compiler for Windows* 11.1

Operating System :

Linux*, Mac OS* X, Windows*

Problem Description :
The documentation in the 11.1 update2 compiler says the header file for Intel® AVX intrinsics is "gmmintrin.h". It is wrong.

If you use it, you will get following compile error:

>>icl /c /Od /EHsc t.cpp
Intel(R) C++ Compiler Professional for applications running on IA-32, Version 11.1 Build 20090903 Package ID: w_cpro
_p_11.1.046
Copyright (C) 1985-2009 Intel Corporation. All rights reserved.

t.cpp
t.cpp(3): catastrophic error: could not open source file "gmmintrin.h"
#include
^

compilation aborted for t.cpp (code 4)

Resolution Status :

This is a known bug. It will be fixed in the future compiler update.

Please use the correct header file "immintrin.h".

Thread affinity compiler switches have no effect

Thu, 24 Sep 2009 10:39:53 -0700

Reference Number : DPD200119846

Version :
Intel® C++ Compiler for Linux*and Windows*, 11.1 initial releases and update 1
Intel® Fortran Compiler for Linux*and Windows*, 11.1 initial releases and update 1

Operating System : Microsoft Windows XP*, Microsoft Windows Vista*, Microsoft Windows Server 2003*; Red Hat Enterprise Linux* 3, 4, 5, SUSE LINUX Enterprise Server* 9, 10, 11, other supported Linux distributions (see Release Notes)

Problem Description : Thread affinity compiler switches /Qpar-affinity (Windows*) or -par-affinity (Linux*) are used to specify compiled-in thread affinity of the executable. However, when the executable is run, no effect is observed. In other words, the default runtime thread affinity is used, or if KMP_AFFINITY has been set, the runtime thread affinity matches its setting (the switches are supposed to take precedence).

Resolution Status : The issue has been resolved in the 11.1 update 2 release. The compiler builds are:
Linux* C++: l_cproc_p_11.1.056
Linux* Fortran: l_cprof_p_11.1.056
Windows* C++: w_cproc_p_11.1.046
Windows* Fortran: w_cprof_p_11.1.046
