Sorry for not being specific.  What I mean is that we consistently see
this behavior across all of our systems, which are all running
identical software, including gdb 7.8.1.  This probably isn't
surprising :)

I should also mention that we're running gdb as root.  Not sure if that matters.

I'm not familiar with inputrc, unfortunately.  Can you tell me if
there's anything weird in there?  I have nothing in ~root/.inputrc,
but here's the contents of /etc/inputrc:

# /etc/inputrc - global inputrc for libreadline
# See readline(3readline) and `info rluserman' for more information.

# Be 8 bit clean.
set input-meta on
set output-meta on

# To allow the use of 8bit-characters like the german umlauts, comment out
# the line below. However this makes the meta key not work as a meta key,
# which is annoying to those which don't need to type in 8-bit characters.

# set convert-meta off

# try to enable the application keypad when it is called.  Some systems
# need this to enable the arrow keys.
# set enable-keypad on

# see /usr/share/doc/bash/inputrc.arrows for other codes of arrow keys

# do not bell on tab-completion
# set bell-style none

# some defaults / modifications for the emacs mode
$if mode=emacs

# allow the use of the Home/End keys
# "\e[1~": beginning-of-line
# "\e[4~": end-of-line

# allow the use of the Delete/Insert keys
# "\e[3~": delete-char
# "\e[2~": quoted-insert

# mappings for "page up" and "page down" to step to the beginning/end
# of the history
# "\e[5~": beginning-of-history
# "\e[6~": end-of-history

# alternate mappings for "page up" and "page down" to search the history
# "\e[5~": history-search-backward
# "\e[6~": history-search-forward

# # mappings for Ctrl-left-arrow and Ctrl-right-arrow for word moving
# "\e[5C": forward-word
# "\e[5D": backward-word
# "\e\e[C": forward-word
# "\e\e[D": backward-word

# $if term=rxvt
# "\e[8~": end-of-line
# $endif

# for non RH/Debian xterm, can't hurt for RH/DEbian xterm
