917780 - Crash in xpc::WrapperFactory::WaiveXray (again)

Status: RESOLVED INACTIVE

(Core :: XPConnect, defect)

Description

Attachment: firebug-1.13.jsd2.0a2.xpi

This was first posted to bug 885388.

It happens when switching between tabs while Firebug is enabled for them. It's not always reproducible for me, though.
My steps:
1. Install the attached version of Firebug (which is using JSD2)
2. Go to https://getfirebug.com/tests/manual/console/joes-original/test.html
3. Open Firebug for that page by pressing F12
4. Go to https://getfirebug.com in a second tab

=> Firefox crashes.

Given stack frames 3 and 4, this might be related to off-mainthread script parsing:

3  	PR_AttachThread 	nsprpub/pr/src/threads/prcthr.c
4 	xul.dll 	 	mozilla::dom::workers::scriptloader::ReportLoadError(JSContext *,nsString const &,tag_nsresult,bool)

@bhackett, do you agree?

No, both frames look bogus (the calling frame does not actually call that function), and frame 4 is DOM workers code and unrelated to off thread parsing.
