Package: mpich

Severity: important

mumps is FTBFS on hppa and powerpc, segfaulting in build-time tests,
https://buildd.debian.org/status/fetch.php?pkg=mumps&arch=powerpc&ver=5.8.2-1&stamp=1776994818&raw=0
The segfault is hard to interpret, but reproducing on powerpc
porterbox suggests mpich and pmix might be the problem
e.g.

The libpmix2t64 used on powerpc is 5.0.1-4.1
but pmix is now 6.0.0+really5.0.9-3
Indeed, pmix was switch to 64-bit only in 5.0.2-2
But mpich's debian/control declares
Build-Depends:
libpmix-dev [arm64 ppc64el riscv64 s390x powerpc ppc64 sparc64],
libpmix-bin [arm64 ppc64el riscv64 s390x powerpc ppc64 sparc64],
i.e. 32-bit powerpc is still listed there in the libpmix-dev dependency,
even though it no longer builds it.
Evidently powerpc needs to be removed from these mpich pmix dependencies.
This would be severity: serious, except that powerpc is not an
official port.
Then there's a mumps test failure on hppa.
But hppa doesn't have the same pmix problem so don't know what's going on
there yet. The hppa mumps error message at
https://buildd.debian.org/status/fetch.php?pkg=mumps&arch=hppa&ver=5.8.2-1&stamp=1777034697&raw=0
is
