778742 - Fatal "compartment mismatched" assertion trying to use Add-on Builder Helper in Nightly

Status: RESOLVED DUPLICATE of bug 778409

(Core :: XPConnect, defect)

Description

[Jonathan Watt [:jwatt]]

It seems that if you try and use Add-on Builder Helper - or any of the many add-ons that depend on it - in debug Nightly, it will crash due to a fatal "compartment mismatched" assertion. With that add-on (and only that add-on) enabled, crashing is pretty much just a page load away.

This is a pretty major pain in the neck, since I now can't use a lot of the add-ons that I depend on for debugging.

Jonathan, do you have a stack to the assert point?

Okay. I'll un-CC David then, since I'm sure he get's CC'ed on enough bugs.
