Subject: bug#3474: 23.0.94; Emacs.app crashes during typing (with patch)
Date: Fri, 5 Jun 2009 13:57:31 +0200 [thread overview]
Message-ID: <416FFC32-AFAF-4A82-97AD-057D332C37C2@gmail.com> (raw)

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:
I've encountered a few crashes in Emacs.app, which happened while
typing when Emacs was a bit busy. It turns out that these crashes
were due to an omitted null-pointer check at line 4165 of keyboard.c
in function kbd_buffer_get_event(). The attached patch fixes this
problem along with a second omitted null-pointer check in line 4323
of the same function.
Wolfgang
