A segmentation fault is most likely a problem with your application, not
TORQUE.

However, one thing that might be worth checking on the TORQUE is that
your pbs_moms don't have absurdly low stack limits set, because those
will be passed down to the jobs.  I've seen that cause trouble for
applications in the past, particularly with FORTRAN programs that put
everything on the stack, and so I've gotten in the habit of putting the
following commands in my pbs_mom init scripts right before the daemon is
started, just in case:

		ulimit -s unlimited
		ulimit -v unlimited
