I'm not entirely sure who the Vampirtrace folks are, or if they are aware of
the Coverity tool that is periodically reviewing the OMPI code base and
providing warnings of potential code path errors.
In the most recent review, dated 5/28, the Coverity tool found over 50
issues in the Vampirtrace code. Might be worth a glance - many of these
appear to be potential sources of segv's if someone hits the right code
The devel list contains a thread on how to access the Coverity review tool.
