The .34 failed. I set ulimit -c 100000 and found no core on the system.
I am running it again in case I made a mistake. It is compiled with debug.
More later. Thanks!

Still better to run under gdb. But given the fact that you're getting heap corruption, you're really going to need something like efence in addition. Unfortunately that's going to make things run very slowly, but that's the only sure way to identify the root cause of the problem.

I attached a gdb to the new process plus the -d 7 output (you know,
that neat thing that unix has called redirection). Hopefully, the
connection I have to the computer will not be lost and I will be
able to get the trace if it fails. Also, not the results below are
just the last part of the output. Let me know if I need more. For
what it is worth, I did the 'he' search shown at the bottom below
and it did not fail.... Thanks!

Finally failed, I did not have a gdb on it, but did have -d 7. Below
are the results. Thanks!
