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.
