Moe -
Thanks for the patch. I've committed it into our subversion
repository. I've also made a 7.1.4b2 tarball and posted it on our
web page at:
http://www.lam-mpi.org/beta/
I'm not entirely sure I want to do yet another LAM/MPI release, so
unless this becomes a large issue, I'll probably just leave the patch
in the beta for now. If more bugs crop up, we may do another bug fix
release.
Thanks again,
Brian
