No need to debug it, just run it under GDB, like this:

 c:\whatever> gdb emacs.exe
 ...
 (gdb) run -Q

Then do whatever is needed to reproduce the crash.  When Emacs
crashes, GDB will kick in and display its "(gdb)" prompt in the cmd
window where you started it.  Then type at that prompt:

 (gdb) thread apply all bt

and post here everything it displays.  We will take it from there.
