[mvapich-discuss] Error building with PGI 19.x and MVAPICH2 (v 2.3.1) on Centos 7

[Carlson, Timothy S]

Hello,
I have found that a basic build of mvapich2 with the PGI compilers fails when building mvapich2 2.3.1. To reproduce

./configure --with-device=ch3:psm --prefix=/share/apps/mvapich2/2.3.1/pgi/19.1

With CC/CXX/FC/F77 set correctly for the PGI compilers.

The error comes when compiling mpispawn.c

make V=1

@children = common global %astruct.dt27083* zeroinitializer, align 8

If I replace -O2 with -O it goes past the error without problem.  This is true for the PGI 19.1 and 19.5

I have not dug too deeply into this.. I'm a sys-admin not a developer 😊

Thanks
