I get the following error when trying to compile a fortran subroutine:
internal error: Please visit 'http://www.intel.com/software/products/support' for assistance.

This same code works on a different system with *nearly* the same compiler. That is it works under

%ifort -V
Intel Fortran Intel 64 Compiler Professional for applications running on Intel 64, Version 11.1 Build 20090827 Package ID: l_cprof_p_11.1.056

but fails when compiled (on a different system) with
%ifort -V
Intel Fortran Intel 64 Compiler Professional for applications running on Intel 64, Version 11.1 Build 20091012 Package ID: l_cprof_p_11.1.059

As can be seen, the installed compilers are the same version and slightly different builds.
The two systems are very similar, both are login nodes on large compute clusters. Both are Intel Xeon CPU's on RHEL 64 bit systems.

This can be reproduce even for a simplified compile such as
ifort -module t/Linux.Intel.mpi/m -O0 -c ../hg_hypre_stub.f90
I can provide source as required.

thanks,

PS We have Intel premier support but I have not been able to post this question there and have not had a response back from intel even after the 48 hr time period.
