Confirmed with latest 3.1b3pre on Linux.

Odd that it's the chrome JIT that is needed, and not the content JIT.

I get the same stack as you on Windows XP, but get completely different stacks for Shiretoko and Minefield on Linux.

[Tony Chung [:tchung]]

I can confirm the crash using the steps in comment 0.  with jit.chrome enabled, the URL will crash after trying to fully load.  with jit.chrome disabled, the site loads without crashing.

Comment 5

[Mike Beltzner [:beltzner, not reading bugmail]]

bsmedberg suggested we block on this since it can likely happen from content as well

Comment 6

[Robert Sayre]

Attachment: assertion

Nothing happens to me if I run this from a started browser, but if I start up with ./firefox going directly to the page, I get the assertion in this attachment.

chrome jit on.

Comment 7

[Brian Carpenter [:geeknik]]

Crashes 3.1b4pre build 20090314050040.

http://crash-stats.mozilla.com/report/index/1e0110b5-ea03-47b6-9158-d154e2090314?p=1

I do have chrome jit on as well.

Comment 8

[Dave Garrett]

This seems to be fixed in the latest Tracemonkey branch build.
(tested w/ WinXP & Linux)

Comment 10

[Brian Carpenter [:geeknik]]

Going to http://piro.sakura.ne.jp/index.html with 3.1b4pre build 20090315052502 still crashes.

http://crash-stats.mozilla.com/report/index/cf208fd6-ff6c-4e80-ada8-a187c2090315

Vista Ultimate SP2 32bit and javascript.options.jit.chrome = true.

Comment 11

[Robert Sayre]

This should be fixed in m-c now too, but not yet in Shiretoko. Look for fixed1.9.1 to mark that.

Verified fixed on trunk and 1.9.1 with builds on Windows and OS X:
