We have an application that runs fine under Windows NT. When run under win32s in Windows 3.1, it crashes at random, non repeatable times. We need a tool that can produce essentially a core file, or some type of stack dump at the time of death, so that we can analyze what happened. Is there such a tool? I've seen a utility that ships with Lotus Notes (qnc.exe, Quincy), that does this under OS/2, NT, and possibly others, for Lotus Notes crashes. It provides, in a "notes.rip" text file, a dissection of the stack, so that you can tell what the call stack was at the time of death. (It's invaluable for programming notes server add-ins). I need something similar that I can use on/compile into, my own applications.
