Maybe it is caused by my MPI installation.
Well, it does seem to be dying the first time it really queries an MPI
communicator.
I seem to recall some old MPI implementations that *required* you to
run your application via their launcher if you were initializing their
library. Try using
LIBMESH_RUN='mpirun -np 1' make check
or
LIBMESH_RUN='mpiexec -np 1' make check
and see if either of those work any better?
