This looks like a dead mObjectFrame in nsPluginInstanceOwner. In light of what we discovered in bug 683059, mObjectFrame gets destroyed before the nsPluginInstanceOwner dtor which is where mObjectFrame is nulled out. So in addition to setting the plugin instance in the object frame to null in Destroy, I think we should be nulling out the object frame as well.
It's now #3 top crasher in 13.0a1. Th only comment says: "This version of Nightly seems to have a little heartburn w/ Intellicast's Flash-powered weather map."
Hey Marcia, can we try and reproduce this?
While I was checking one of the URLs from this signature I crashed in Bug 724812 Comment 1 - wondering if these two signatures are related.
(In reply to Marcia Knous [:marcia] from comment #4) > While I was checking one of the URLs from this signature I crashed in Bug > 724812 Comment 1 - wondering if these two signatures are related. This one is specific to 64-bit builds, so it might be the 64-bit version of bug 724812, assuming Breakpad is not good for 64-bit stacks.
I see 185 crashes across the trunk in the last week. 98% of the crashes are on Win 7. One user comment: it keeps shutting down when ever i set my location. That user has no extensions installed. http://local.msn.com/weather.aspx?q=Bronx-NY&zip=10460
Here are some manual addon correlations: nsCOMPtr_base::assign_assuming_AddRef(nsISupports*) | nsObjectFrame::PrepForDrawing(nsIWidget*)|EXCEPTION_ACCESS_VIOLATION_READ (21 crashes) 10% (2/21) vs. 0% (5/1635) TFToolbarX@torrent-finder (Torrent Finder Toolbar, https://addons.mozilla.org/addon/2755) 10% (2/21) vs. 0% (8/1635) firstname.lastname@example.org 19% (4/21) vs. 12% (189/1635) email@example.com (Mozilla Labs - Test Pilot, https://addons.mozilla.org/addon/13661)
Here are some better STR that I just got using the latest nightly on Win 7: 1. Load http://local.msn.com/ten-day.aspx?q=Middletown-CT&eid=21225&zip=06457 2. Select "Find a location" 3. Keep changing the location to different zip codes 4. Eventually after 3-4 times I generate a crash The crash usually happens when I start typing the same of the city in the field.
Actually the crash signatures I am getting match Bug 724812. (In reply to Marcia Knous [:marcia] from comment #8) > Here are some better STR that I just got using the latest nightly on Win 7: > > 1.

We have STR, it's a top crash - #9 on the trunk. It's not assigned to anybody.
Created attachment 603276 [details] [diff] [review] fix v1.0 This might do the trick. Clear out the frame pointer as soon as we know the frame will be destroyed.
try run for fix v1.0 https://tbpl.mozilla.org/?tree=Try&rev=0c4792b1fceb
pushed to mozilla-inbound http://hg.mozilla.org/integration/mozilla-inbound/rev/c8ff0f77a129
Removing qawanted -- the original ask was for a reproducible case which has been found some time ago. We will verify the fix as per our normal schedule -- no need to track any longer with qawanted. Please re-add if there is more we can do.
There is no testcase to reproduce this crash, right?
(In reply to Al Billings [:abillings] from comment #17) > There is no testcase to reproduce this crash, right? My understanding was that comment 9 is the reproducible case. I could be wrong...
I can't reproduce a crash in Firefox 11, pre-fix, with that testcase.
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:13.0) Gecko/20100101 Firefox/13.0 (beta 4) Could ot reproduce the crash using steps from comment #8. Also, no crashes with this signature were reported in the last 4 weeks. Is there anything else that can be done before marking this verified for FF13? Thanks!
I think that's good enough Mihaela. Thanks.
