Subject: Re: [OMPI users] With IMPI works fine,With OMPI fails

An "Internal compiler error" indicates a bug in Intel Fortran (a segfault
in this case), and not in anything the compiler is trying to build- if the
code you're building has an error, the compiler should properly print out
an error statement.

You should forward this along to Intel.
