I'm going to try with OpenMPI and see if this is replicated or not.
The introduction/ex4 and indeed make check all pass in dbg/devel/opt with
LIBMESH_RUN="mpiexec -np 2" using OpenMPI 1.8.4. :-/
Want to hear something even weirder? introduction_ex4 works fine with
MPICH when using --enable-complex.
This ought to be such a simple problem to debug, too:
mpirun -np 2 ./example-devel -d 1 -n 2 -o FIRST
Generates just 2 elements, 3 nodes. Hangs in devel and opt modes with
MPICH, inside that (empty) send_receive_packed_range of constrained
nodes.
