Create a core file of GDB? (y or n) y
----

The user didn't want to create a core file and use up all they bytes
left on his disk.

But you slipped an extra same sized question in at the end, which of
course the user thinks is just the third y or n to get out. (I mean you
already asked him if he wanted to quit, so he didn't expect any further
questions, he thought there was something wrong with some keypress
again, so unless he looks carefully, he will just hit y again.)

Maybe change the last question to "(c or n)".
