"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's hard not to conclude this is a PGI 17 bug from your description. Have you reported this to PGI? I would hate for the MPICH team to take support work away from the people PGI pays to do this.

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.
