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

[Jeff Hammond]

"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.
