I think the debugger doesn't stop working, it just doesn't switch the 
screen back to text mode, so you don't see the usual GDB display and 
prompt.  So what you need is a method of switching the screen to text 
mode.

An easier way might be to redirect GDB output to a printer:

	gdb myprog > prn

Did you try this?
