578812 - dehydra: JS assertion failure: non-global object at end of scope chain, at ../jsobj.cpp:6303

Status: RESOLVED FIXED

(Developer Infrastructure :: Source Code Analysis, defect)

Description

[Ehren Metcalfe]

This is introduced with d770ef6237ea from Bug 570169. Oddly enough bug 576714 reports the same error and claims it was fixed in tracemonkey. I've just built dehydra using tracemonkey and get no difference from the mozilla-central build.
