bug#665: 23.0.60; Emacs frequently crashes when using MEW


From: 鯉江英隆
Subject: bug#665: 23.0.60; Emacs frequently crashes when using MEW
Date: Thu, 07 Aug 2008 18:34:11 +0900 (JST)

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:

    Emacs frequently crashes when using MEW (it is a mailer).
    I'm using Emacs in TTY.

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/local/share/emacs/23.0.60/etc/DEBUG for instructions.
