trouble with comint-sent-input for gdb

trouble with comint-sent-input for gdb

Greetings!  When I start gdb within emacs (e.g.,     (gdb "gdb /tmp/hello")
), I find the same behavior described by IvanAndrus in
http://www.emacswiki.org/emacs/DebuggingWithEmacs , namely, entering a
command (such as   break main  ) and pressing RET causes the command to turn
bold correctly, but nothing else happens.  The program isn't already
running, and RET is correclty bound to comint-send-input (I bound another
key to comint-send-input and tried that, just to be sure, with the same
results).  This is happening on
GNU Emacs 23.2.1 (x86_64-redhat-linux-gnu, GTK+ Version 2.20.1)
 of 2010-05-13 on x86-07.phx2.fedoraproject.org

but it does not happen on
GNU Emacs 22.2.1 (x86_64-redhat-linux-gnu, GTK+ Version 2.12.9)
 of 2008-05-23 on xenbuilder2.fedora.redhat.com

Any ideas?  Thanks.

Here is a little more info about my question yesterday:

    1.  The following shows in the gdb window:

Current directory is /tmp/
GNU gdb (GDB) Fedora (7.1-26.fc13)
Copyright (C) 2010 Free Software Foundation, Inc.

This GDB was configured as "x86_64-redhat-linux-gnu".
For bug reporting instructions, please see:
<http://www.gnu.org/software/gdb/bugs/>...
Reading symbols from /tmp/hello...done.
(gdb) break main

break main

    The final "break main" above indicates that there was no response from
the first one, so I eventually tried it again.

    2.  When I request the value of comint-output-filter-function, I get *

*comint-output-filter-functions's value is
(comint-postoutput-scroll-to-bottom comint-watch-for-password-prompt)

    whether I am in the gdb window or another window.

Thank again for any clues to what may be happening.
