I just committed a fix to the trunk to fix your original segfault down
in opal_show_help() - this is the same problem Ken posted. This fix
should make it into the v1.0 branch eventually. Even so, you are going
to run into the real problem you were handling - this fix is just for
proper error handling/output.
The error below looks like a word size mismatch - one thing is compiled
64bit, the other is compiled 32bit. Make sure everything is compiled
either 32bit or 64bit.

I rebuilt without a vpath build (running ./configure) in the src dir,
and now I get:
