bug#1447: 23.0.60; emacs crash

[Feng li <fengli@blackmagic-design.com>]

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@gnu.org mailing list.

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

Start emacs by running "emacs -q". Press "C-h b" to show the
key-binding list. Switch to the help window, press PgDn a few times
and Emacs will crash.

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.
