segmentation violation

[Matt Savoie]

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

Your bug report will be posted to the address@hidden mailing list.

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

Again, like the report I submitted for Emacs 21.4, I was working franticaly
(lots of fast typing) and emacs just has a segmentation violation


If emacs crashed, and you have the emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.

If you would like to further debug the crash, please read the file
/home/savoie/downloads/emacs/etc/DEBUG for instructions.


I'll look at this, but wanted to get this to you, 'bt full' follows 'bt'.
The recent input, modes and settings pertain to another session I started
with the same command:

cd "/home/savoie/downloads/emacs/src/"
echo "run $@" > gdb_comm
gdb -x gdb_comm emacs
