How to debug seg fault. [message #48079]

I'm running IDL 6.0 on a sun workstation under solaris 8.

I have a pretty elaborite GUI program, that with the same set of
actions, I can reproducibly cause IDL to terminate with a segmentation
fault.

I'm trying to debug this problem, but it's almost impossible because if
I add a print statement to the code, I no longer get the crash.
Likewise, if I step through in IDLDE, I don't get the crash.

This seems like a classic memory access problem, but I can't figure out
how to pinpoint the problem - which may be having other unseen
ramifications.

Any advice appreciated.

Thanks.

-Jonathan
