* TITLE/SUMMARY
warwar.gif animated GIF halts after after ~10 seconds

[adapted from old BugSplat bug #87155]

* STEPS TO REPRODUCE
0) Launch Apprunner
1) View http://www.prometheus-music.com/gecko/warwar.gif [snarfed from http://
www.gifanimations.com/images1/warwar.gif]

* RESULT
 - What happened

After about 10 seconds of animation, the animation halts about 4 seconds after
the rightwards travelling lightning bolt, and remains frozen at that frame. The
frame at which it halts differs from execution to execution, but it's always
around that space.

The throbber & progress bar continue to animate [even after 90 minutes.]

 - What was expected

Behavior equivalent to Communicator 4.x and IE 5.


* REGRESSION

 - Occurs On
        Mac OS Apprunner (6.1.99 AM optimized build)
        Linux Apprunner (6.2.99 AM optimized build)
        Win32 Apprunner (6.4.99 AM optimized build)


 - Doesn't Occur On
        Communicator 4.6 RTM (Mac OS 99124 & Win32 99127)
        Internet Explorer 5 RTM (Win32)


* CONFIGURATIONS TESTED

- [Mac] Power Mac 8500/120 (233 Mhz 604e), 64 MB RAM (VM on; 1 MB of VM used),
1024x768 (Thousands of Colors), Mac OS 8.6

- [Win32] Vectra VL (233 Mhz P2), 96 MB RAM, 800x600 (True Color), NT 4.0 SP3.

- [Linux] Vectra VL (266 Mhz P2), 96 MB RAM.

I came across something really similar to this at http://www.javascript.com. It
looks to me as though animated gif's are not looping. Could this have been
broken in an attempt to fix bug #5030, in which they hit the server each time
they loop?

This is on 1999070308 on Win '98.

I hate this. A new bug has cropped up that
causes a crash (access violation) before this
bug can be addressed.
I'll enter a new bug and make this one dependent on it.

Umm...what in particular is the common bug? In this case, it's not crashing after
a full iteration, but I (thought) was crashing after a particular, and
potentially corrupted frame.

Comment 7

[pnunn]

odd. This worked yesterday. After yesterday's changes
it stops working.
I'll reopen.

Verified fixed on Mac OS [8.6], Win32 [NT 4.0 SP3], Linux [Red Hat 6.0/GNOME],
using 1999092208 builds.

Linux crashes after a minute, but that's another bug.
