M-x gdb works differently in Emacs 21, but similarly in Emacs 22.1 and
Emacs 23.0.60.  Emacs 22.1 has been included with many distributions including
Ubuntu Hardy and there have been few bug reports, so I suspect it has something
to do with your set up.

Have you read the node in the Emacs manual about bug reporting?

In particular what happens if you don't load your .emacs, i.e., start Emacs
with "-q"?

What version of GDB are you using?

emacs-pretest-bug@gnu.org is an active mailing list and the right one for
reporting bugs in Emacs 23.0.60.  Maybe there is something wrong with your
mail server.

What text do you have in the mini-buffer when you type <return> for the
second time?
