Open MPI v1.3 does not include a memory manager by default, so it's
possible that something else is going on here to interfere with
Valgrind's behavior. Or it could be that Valgrind simply won't catch

Try --without-memory-manager (not --disable).

This won't work in practice; OMPI *needs* the open-pal library, and
for shared library builds, it will pull it in by default anyway.
