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 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.

Is the arrow visible when you step through the program with `n'?  More 
generally, could you describe the circumstances which make the arrow 
disappear (unless it is never visible)?  I did some simple tests, and it 
seems that for me, the arrow is always visible.  So perhaps you do 
something special do trigger this problem.

No.

It is never visible (except for the flashes I noted previously).

I will report the problem to Red Hat as well, since I am using a Red
Hat Emacs package.  Perhaps they've customized Emacs in some way that
is causing this problem.
