Crashes my Mac trunk debug build too. The crash seems to be during cycle collection.

Actually, looks like http://www.mameworld.net/samples/TOCFrame.htm is triggering random memory corruption. It frequently causes an immediate crash, but can lead to a crash anywhere.

http://www.mameworld.net/samples/pics/galaga88.gif is what triggers the crash. Shift+reloading it a few times usually crashes Firefox.

CCing Alfred Kayser, who fixed bug 403578.

Actually this is a DUP of bug 408310. With the patch that I submitted there, mozilla (seamonkey/firefox) doesn't crash on this image anymore.
