Crash handler on Win32

[niko]

Hello,

I have an application and a customer reports it crashes from time to time. If I could get a backtrace - like the KDE Crash Handler does ist - i could probably find the bug.
(I'm not able to reproduce the crash on my machine)

How can I create such a backtrace without using a debugger?

thanks,
niko

can this be used with mingw?

I get these errors when compiling the included crashcon application:

I installed wtl (-I"..\..\wtl75\include") and even microsoft sdk (-I"m:\Programme\Microsoft Platform SDK\src\mfc") - to get atlbase.h which was missing.

Finally I found something useful that works with mingw:

You can also use exchndl.dll directly - without requireing to install drmingw - very nice :D
