Yeah, I find it weird too. Here's my latest post to the OpenMPI users
mailing list:

http://www.open-mpi.org/community/lists/users/2010/03/12199.php

Maybe it does not use cr_* directly but blcr-util provides something
else that ompi-restart requires? Either way, I don't think
ompi-restart is supposed to segfault...

If you prefer, I can run my tests with the openmpi-checkpoint after
#572021 is fixed and then report back whether or not blcr-util is
needed.
