x = [];
x.toString = x.sort;

crashes js debug and opt shell on m-c changeset 44d992ccc97a without any CLI arguments at IsPoisonedId or js::array_sort with too much recursion.

Too much recursion crash, usually not security-sensitive, but IsPoisonedId freaks me out just a little.

Bug 684462 might be related.

autoBisect shows this is probably related to the following changeset:

Looks like a recursion DoS? If you agree, Jeff, we can unhide this bug. If not please change [sg:dos] to something more appropriate

Yeah, this is just recursion.

See bug 717497, bug 721935 and bug 728722 for other possibly-related too-much-recursion crashes.

May I please convince someone (if Waldo is too busy) to fix these too-much-recursion dos crashes? (also see bug 671797, bug 684462 and bug 743301.

They are producing so many duplicates that we have to ignore js::Invoke on the crash reports, and js::Invoke seems to be a pretty commonly used function that ignoring it may hide other bugs.
