Reference Number : DPD200110663


Version : 11.0.066


Operating System : Windows, Linux


Problem Description : When an application is compiled using /Qipo for Windows* (-ipo for Linux*) and /Qparallel for Windows* (-parallel for Linux) and the final link is performed by invoking the xilink utility directly, this may result in an internal compiler error.

Independent use of either "ipo" or "parallel" and linking with xilink will avoid the internal error. This issue applies only to the 11.0.xxx release of the Intel(R) C++ Compiler with Build Date: 20081105 or later.

The two compilation steps shown below demonstrate how the error can occur:

icl -c /Qipo /Qvc9 /Qparallel .\matmul.c

xilink: error #10014: problem during multi-file optimization compilation (code 4)
xilink: error #10014: problem during multi-file optimization compilation (code 4)


Resolution Status : This issue is resolved in the Intel(R) C++ Compiler 11.0.072. In lieu of upgrading, as a work-around, use either the "parallel" or "ipo" option only.

apparently there has been a regression as this problem, same error msg as above, occurs in 1>Compiling with Intel(R) C++ 11.1.054 [IA-32]... (Intel C++ Environment) which we are currently evaluating.

I have retested the original test case and it still works with the 11.1.054 compiler, so I will need a test case from you with command line invocation so that I can reproduce here. Look like you have encountered a new cause of an internal compiler error. You can file a test case either at premier.intel.com or by posting it to our forum at software.intel.com.
