I am sorry for the delay; I've been caught up in SC deadlines. :-(
I don't see anything blatantly wrong in this output.
Two things:
1. Can you try a nightly v1.8.4 snapshot tarball? This will check to see if
whatever the bug is has been fixed for the upcoming release:
http://www.open-mpi.org/nightly/v1.8/
2. Build Open MPI with the --enable-debug option (note that this adds a
slight-but-noticeable performance penalty). When you run, it should dump a
core file. Load that core file in a debugger and see where it is failing
(i.e., file and line in the OMPI source).
We don't usually have to resort to asking users to perform #2, but there's no
additional information to give a clue as to what is happening. :-(
