Ion,

I've narrowed this down to some checkins that were done on May 5th. The 
following files were added on that date:

The function where the seg fault is happening is 
boost::interprocess::offset_ptr<boost::intrusive::detail::compact_rbtree_node<boost::interprocess::offset_ptr<void> 
 > >::get_pointer() and that was called a few layers underneath 
boost::interprocess::rbtree_best_fit<boost::interprocess::mutex_family, 
boost::interprocess::offset_ptr<void> >::priv_add_segment( ). Also note 
that rbtree_best_fit.hpp is in the above list. Even so, the seg fault is 
happening inside of a call to a multiset insert so perhaps its actually 
the multiset class that has the problem. Does this ring any bells? In 
any event, I'll keep looking...
