If you are getting problems relating to corrupted memory that is 
screwing up the debugging, you might want to try linking with the 
"electric fence" library.

That can lead to an earlier (and cleaner) segfault on memory boundary 
overrun as it uses the machine's virtual memory manager to place each 
allocated block in a separate segment, and it is then enforced by the 
CPU's virtual memory hardware. Hopefully you can trace the cause of the 
bug earlier.
