Subject: 23.0.60; GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600) of 2008-11-28 crash on "C-h b"
Date: Fri, 28 Nov 2008 15:15:32 +1100

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 emacs-pretest-bug <at> gnu.org mailing list.

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

Start a new clean emacs instance by invoking "emacs -q". Press "C-x C-f
RET" to open a dired buffer. In the dired buffer, press "C-h b", emacs
crashes immediatelly. I'm running today's CVS HEAD on windows xp.

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
c:/emacs/etc/DEBUG for instructions.

More likely one of these earlier changes:

2008-07-30  Jason Rumney  <jasonr <at> gnu.org>

   * w32uniscribe.c (uniscribe_encode_char): Fix glyph buffer size.

2008-07-29  Jason Rumney  <jasonr <at> gnu.org>

   * w32uniscribe.c (uniscribe_shape): Avoid using context if cache
   is populated.
   (uniscribe_encode_char): Always use uniscribe.
   Avoid using context if cache is populated.
