So, while it is a bug, if DPMI is active, there seems to be no way to reach that msg at all. So I would say this is a buffer overflow most likely, and DPMI is disabled. gdb might help. This all will be much easier if I get around to implement the automatic gdb dispatcher, but for now you told there is another buffer overflow in mfs, isn't it?
