How do I debug a difficult-to-reproduce crash with no useful call stack?

Question

I am encountering an odd crash in our software and I\'m having a lot of trouble debugging it, and so I am seeking SO\'s advice on how to tackle it.

Answer 1

Threading may be the reason here. The usual suspect are threads that use OVERLAPPED structures on the stack and threads that send pointers to objects that are on the stack to other threads.

It may be possible to recover partial stack information if you use the Deubgging Tools For Windows and use the "dps" command.
