Thanks, installed (and removed the non-prototype code since Emacs's
C code now requires prototypes anyway).

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 bug-gnu-emacs <at> 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 have a script that I run using emacs --script.  When writing the
script, I get errors on occasion.  It would be very useful if
stack-trace-on-error worked in this situation.  Currently it does not.


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
/usr/share/emacs/23.1/etc/DEBUG for instructions.
