FWIW, I don't see MPI in the call stack of the segv at all. This doesn't definitively mean that MPI is not involved, but it does suggest that the bug is elsewhere. You might want to run this under a debugger or examine the generated corefiles to see exactly what the problem was.

I had a similar problem as James described in an earlier message: http://www.open-mpi.org/community/lists/users/2008/07/6204.php
While he was able to recompile openmpi to solve the problem, I had no luck with my RedHat Enterprise 5 system.
Here are two other threads with similar issues regarding openmpi on Ubuntu and OSX which were solved: https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/234837
