Description

Seen while looking at crash stats. Both sigs seem to be related. First signature appears in 8.0 and 8.01, Mac only - https://crash-stats.mozilla.com/report/list?signature=firefox@0x1. Most crashes appear to be startup crashes.

The other signature https://crash-stats.mozilla.com/report/list?signature=-[NativeMenuItemTarget%20menuItemHit:] seems to have a mix of Firefox and Thunderbird crashes but a very similar signature:

These crashes go back at least as far as FF 4.

They're low volume -- 96 in the last 4 weeks.

I'd guess they're happening on access to a deleted NativeMenuItemTarget object.  (Note that a number of comments report crashes on quit.)

It'll probably be a while before I can get to this.
Version: 9 Branch → unspecified
Should we ducktape this crash away with some aggressive null check in the mean time?

I don't know, and it'll take me at least an hour or two digging through the code to find out.

But access to bugzilla has been troublesome all day, which blocks the rest of my work.  So I'll spend the next couple of hours looking into this :-)

Hacky fix

In my enforced "idleness", I've been able to figure out the likely
cause of this bug, and how to fix it.

The crashes aren't caused by accessing a deleted NativeMenuItemTarget
object (we appear to never delete those).  Instead it seems that
menuGroupOwner (an nsMenuGroupOwnerX object) might have been deleted.
An nsMenuGroupOwnerX object is always also an nsMenuBarX object, which
(as a comment warns above its class definition in nsMenuBarX.h)	can
become invalid whenever its DOM node is destroyed.

This patch is a hack.  As my patch comment says, fixing this bug
properly might trigger delays as windows/tabs are closed.  My hack
avoids these (potential) delays.  If it doesn't fix	enough of these
crashes, or if it causes problems of its own, we'll need to risk the
delays.  But I think it's worth trying my hack out on the trunk for a
while, to see if it helps.

There haven't been any of these crashes on the trunk since my patch landed.  So it seems to be working.
