[mpich-discuss] Segmentation fault when MPICH is compiled with Portland compiler 17.5

[Andrew Wood]

Hi,

I'm getting a segmentation fault in MPI_INIT, when MPICH is compiled with the
current version of the Portland compilers:

> mpif90 code.f90 && ./a.out
Segmentation fault

code.f90 is in the attached .tar.gz file, along with the .log files generated by
configuring and building MPICH.

This occurs with PGI versions 17.1 and 17.5, but not with versions 16.1, 16.5 or
16.7, nor with the current Intel or gcc compilers. It occurs with MPICH versions
3.1.4, 3.2 and the current master branch in the github repository.

The problem does not occur if MPICH is configured with the option '--disable-fast'.

Is this a bug in MPICH or PGI, or have I done something else wrong?

Thanks,
Andy.
