unfortunately not much help, since I guess the gnustep libraries are not 
compiled with debugging information. It looks like the stack is just messed up 
anyway, as I don't think the function 'lab' is in gnustep.

I had suggested NSZombiesEnabled before - you just set the environment variable 
and run the program again, and you should get output if an object is being used 
after being deallocated. Other than that I might suggest putting NSLog 
statements in various place to narrow it down. That's tedious, but on Windows 
it's probably best unless you have a good idea how to debug things.
