One other thing I would try is --without-memory-manager. We do some
evil hacks on Linux to intercept malloc/free so that we can getting
better performance out of InfiniBand and Myrinet. It causes problems
on some non-GLIBC systems (and is generally not used on non-linux).
It might be that your platform is just on the wrong side of "linux
enough" to cause problems.
