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

I recently changed my LANG, which used to be C.  But I don't think it
has anything to do with this particular bug.  This one happened right
at startup.  I start emacs using the following script:

#! /usr/bin/zsh
cd /usr/local/src/emacs/src
emacs &
xterm -e gdb program $! &

Then I hit c in gdb and Emacs continues and eventually shows its first
frame.  This time Emacs crashed before the first frame got created.


(gdb) c
Continuing.

Program received signal SIGSTOP, Stopped (signal).

Hm.

I have no idea what this means...
