You can find the stack as attachment.

Does it also happen when you visit it as a standalone testcase?

Comment 2

[Henrik Skupin [:whimboo][⌚️UTC+1]]

No, it doesn't happen in such a situation. It only asserts during a crashtest run.

Comment 3

[Henrik Skupin [:whimboo][⌚️UTC+1]]

This asserts only for the first passed test. As Martijn mentioned on IRC it could be happen due to a bug in the reftest framework?

Possible related bug: bug 507092.

I don't see this assertion when I run the cocoa crashtests (or all crashtests) on Firefox trunk on mozilla-central.

whimboo, if you're still seeing this, you can reopen, but attach a stack that's been through fix-macosx-stack.pl ;)

Yeah, doesn't occur anymore. Verified.
