Bug#1004556: libmpich-dev: The simplest MPI program compiled with mpich crashes

[Drew Parsons]

Package: mpich
Followup-For: Bug #1004556

My guess is that this bug is ongoing in 4.0-2 because of pmix support.

4.0-2 is still configured --with-pmix=/usr/lib/x86_64-linux-gnu/pmix2
and still Depends: libpmix2 (>= 4.1.2)

pmix support was added in 4.0~b1-2 along with ucx.

I gather ucx was deactivated in 4.0-2 but pmix was not. Looks like pmix
also needs to go (unless the problem is ch4, which was also added in
4.0~b1-2). But the error message references PMIX.


Ironically, I find that an executable compiled against mpich 4.0-1
fails with mpiexec.mpich (as raised in this bug) but actually passes
when run with mpiexec.openmpi.  Awkward.
