Issue

While working on conda-forge/mumps-feedstock#102, I got as far as running the tests, but they start to crash with:

Abort(123809283) on node 1 (rank 1 in comm 0): Fatal error in internal_Bcast: Invalid datatype, error stack:
internal_Bcast(107): MPI_Bcast(buffer=0x16f87ab74, count=1, MPI_DATATYPE_NULL, 0, comm=0x84000001) failed
internal_Bcast(67).: Datatype for argument datatype is a null datatype

I looked through mumps source for MPI_BCAST calls, and found some with MPI_LOGICAL. I then checked mpif.h, which has:

PARAMETER (MPI_LOGICAL=MPI_DATATYPE_NULL)

suggesting that MPI_LOGICAL is unavailable. That doesn't seem right, but I don't know enough about mpich for how it determines when these should be available. The same is true for linux-aarch64, which is also cross-compiled.

The osx-64 package has:

PARAMETER (MPI_LOGICAL=1275069469)

So this suggests something is amiss in the cross-compiled mpich builds.
