gud breakage: ^done,changelist=[]

[Jan Nieuwenhuizen]

Hi,

Anyone using gud from CVS?  It has been broken for me for quite some
time now, but it used to break `only' after about 100 prompts or so;
usually enough to nail the bug.

With current CVS (emacs -q), it breaks after less than 20 prompts when
debugging lilypond

    M-x gdb
    gdb --annotate=2 lily/out/lilypond

(btw, why does M-x gdb guess the name of the executable?  I find that
 annoying, as it is often something like config.status)

    Current directory is /home/janneke/lily/lily/out/
