Try "where". Make sure that you have line numbers from the -g compile (e.g. "init.c:354"); otherwise the trace is near impossible to use.

I apologize, but I am not familiar with gdb. I attached to the process, it crashed with a seg fault. What should I be typing in now? Thanks!

Thanks. I am compiling with efence library right now. I am not too worried about the speed, it is not prod. I would like to run it under gdb, and I will try that, the problem is that if I loose my connection the only thing I can think of is to kill the other gdb, then re-attach. I guess that would not cause a problem. I was hoping with the cd and ulimit that the core would be generated and then gdb on that. Thanks!

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!
