420145 - Cycle collection related crashes after out of memory error?

Status: RESOLVED WORKSFORME

(Core :: XPCOM, defect, P2)

Description

[Martijn Wargers (dead)]

See testcase, which comes from bug 347750, it needs enhanced privileges, so you need to download it to your computer.
It gives an out of memory exception, and after that open and close a bunch of tabs. I usually crash quite quickly after that.
Breakpad doesn't give any crash reports, but I attached a stack of a debug build in bug 347750:

I see a bunch more out of memory exceptions coming from the graph builder in
just the last week, see
http://crash-stats.mozilla.com/report/list?range_unit=weeks&query_search=stack&query_type=contains&platform=windows&signature=RaiseException&query=NodePool&range_value=1

I think that needs a new bug, maybe blocking...

Those look like b2 and b3 stuff.

This should get looked at in 1.9.1 at the very least...

Comment 3

[Benjamin Smedberg]

I don't see us blocking on this unless it shows up in topcrash reports, or we can come up with a reliable diagnosis.

In current trunk build I get a hang instead of a crash, it seems.

Comment 5

[Jesse Ruderman on Windows]

Where is it hanging?

Comment 6

[Wayne Mery (:wsmwk)]

I can't reproduce this on win7 with current nightly build and attachment 232545 [details].
Is a particular build needed to reproduce?
