Crash when decoding gif


From: Robert
Subject: Crash when decoding gif
Date: Wed, 26 Dec 2001 18:54:44 +0000 (GMT)

In GNU Emacs 21.1.1 (i586-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2001-10-22 on jailhouse
Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: en_GB
  value of $LC_CTYPE: en_GB
  value of $LC_MESSAGES: en_GB
  value of $LC_MONETARY: en_GB
  value of $LC_NUMERIC: en_GB
  value of $LC_TIME: en_GB
  value of $LANG: en
  locale-coding-system: iso-latin-1
  default-enable-multibyte-characters: t

Not sure whether this is anything like enough, but an email containing a
(particular), animated gif(eugh!) causes an emacs crash when attempting to
view the picture from within vm (0.90).

Traceback as follows:

I can replicate this very easily so if more information is needed I'll be
happy to dig deeper into the gdb session!
Loading the file works ok in auto-image-file-mode
