I've noticed that (the string, I mean).  Nice touch!

I believe you can make it happen reliably like this:

    1.  Start up GDB to debug a program.
    2.  Start excuting the program under GDB.
    3.  Hit a breakpoint before the program has terminated.
    4.  Quit out of GDB without continuing the program (so that it never
	terminates).
