This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I'm using "emacs -nw -q" in an xterm.  When I use M-x gdb to debug a
program, put in a breakpoint and run the program, the arrow showing me
where I am is not visible when the breakpoint is hit.  If I type
"frame 0", the arrow flashes and then disappears again.

Note that I've got my xterm configured with a foreground color of
green and a background color of black, but I'm not sure how relevant
this is (since if this were a color problem, I imagine that the arrow
wouldn't flash even briefly).  Note, furthermore, that I see this
problem with two different versions of xterm -- the one in Red Hat's
XFree86 3.3.6 package, and the one in Red Hat's XFree86 4.1.0 package.
