Here's what I did: Compile Emacs so that it retains symbol info,
etc. (see C-h C-d).
I ssh'd into my laptop from termux, started an emacsclient there.  cd'd
into src/ directory of my git checkout started gdb by saying M-x gdb
RET.  In the gdb prompt, I said

    (gdb) source .gdbinit
    (gdb) break xlwmenu.c:2879
    (gdb) run -Q

At this point, emacs -Q should have opened in your machine.  I clicked
the menu in the emacs -Q frame and the breakpoint in gdb hit.  Make sure
you don't move the mouse or use the keyboard.  After the breakpoint hit,
it was a matter of doing what Eli instructed me.

HTH.
