Octave comes with an msys environment. You could start a command shell by 
running "cmdshell.bat" in the directory where Octave is installed. Run "gdb" 
and attach it to the running Octave (via its PID - "12345" in the snippet 

(gdb) attach 12345
(gbd) c

... continue working in Octave and try to reproduce the crash. Once it crashes, 
get the backtrace from there:
(gdb) bt

I hope this helps finding what is going wrong.
