Crash Data

This bug was filed from the Socorro interface and is 
report bp-7ea9ee5b-5c00-468b-8aca-66f532150821.
=============================================================

This is our MOZ_DIAGNOSTIC_ASSERT(CheckDocTree()) hitting.

More reports here: http://is.gd/8bPDDR
This is getting hit a lot in the wild. What can we do?
Flags: needinfo?(dbolter)
Deferring to Trevor. (I asked him yesterday on IRC but we got distracted by another freq crasher)

DMajor I think I just noticed crash stats is calling this a startup crash - correct?

> DMajor I think I just noticed crash stats is calling this a startup crash - correct?

This one is a mix. There are indeed a large number of these happening below 60 seconds. There are also cases where we survive for hours, and everything in between.
Trevor in the case where the second check fails:
http://hg.mozilla.org/mozilla-central/annotate/01ae99b53561/accessible/ipc/DocAccessibleParent.cpp#l125
(from https://crash-stats.mozilla.com/report/index/d9d01b5b-def6-445c-81c0-16dee2150910)

Presumably this code is leaving the tree bad:
  ProxyAccessible* parent = root->Parent();
  parent->RemoveChild(root);
  root->Shutdown();

Any ideas?

kind of I knew for a while that was a likely spot for the problem to be, but I couldn't come up with a case that shouldn't work.  But taking another look I figured I might as well try this.
Flags: needinfo?(tbsaunde+mozbugs)
Tracking for 43 and 44 since this looks like a recent regression.
Crash Signature: [@ mozilla::a11y::DocAccessibleParent::RecvHideEvent(unsigned __int64 const&)] → [@ mozilla::a11y::DocAccessibleParent::RecvHideEvent(unsigned __int64 const&)] [@ mozilla::a11y::DocAccessibleParent::RecvHideEvent]
The crash rate looks about the same for mozilla::a11y::DocAccessibleParent::RecvHideEvent, still showing up on nightly and aurora. Not very high volume, but it hasn't changed from other crash fixes in the last month.    I don't see this signature in 41 or 42 anymore, though.

I think that's because only e10s exercises this code.
Tracking for 45 since it's affected, marking as disabled for 43.
Nominating this for e10s tracking. This is another e10s related top crash.
tracking-e10s: --- → ?
Given that e10s will be disabled by default for FF44 (after e10s telemetry experiment), this is a wontfix for FF44. Nom'ing for tracking in FF46.
Tracking for 46 to check up on this in a week or so. I don't see any crashes in the last week for 46 or evidence 46 is affected (from these particular signatures)
Only a couple of crashes with these signatures in the past week (on 43 and 44 aurora versions.)  Maybe this is fixed in 45 and 46 by some other patch.   
David or Brad, is that enough to declare this fixed and move on ?  Or is there some risk that affected users may have moved off Firefox?

swell, I think we may have disabled a11y with e10s for many users on nightly which would hide this, but maybe its fixed I'm not sure.
Flags: needinfo?(tbsaunde+mozbugs)
I suspect disabling e10s for a11y users is why this has gone away, but I don't think that means its fixed
Flags: needinfo?(blassey.bugs) → needinfo?(wmccloskey)
Yeah, probably not fixed.
Flags: needinfo?(wmccloskey)
Marking wontfix for 45 and 46, since we are disabling e10s for users with a11y users in at least those two versions.
David points out this should be marked disabled rather than wontfix. Thanks!

downgrade diagnostic assert in RecvHideEvent()
Yes, just hit that baby, too, in Thursday's Nightly, when opening the document linked to from the Google Form Mardi sent out on Thursday. Staff know what I mean. ;)

There are 174 crashes in nightly 54 with buildid 20170216030210.

There are still a lot of crashes with this signature.  It is 
ranked #2 in the Windows nightlies for 20170216030210.

mihgt have been the other diagnostic assert in that function? That was downgraded in bug 1197184 so I guess we'll see.

This work hasn't made it into nightly yet.
confirming fix, crashes stopped on 2-17.
Does this need backporting to Aurora/Beta?

> Does this need backporting to Aurora/Beta?

yes.  We'll need to post a patch and get approval I guess.
Flags: needinfo?(tbsaunde+mozbugs)
I still see this signature on nightly builds as recently as yesterday. Is there another bug tracking this crash signature or do we need to reopen?

Can you link a crash report from a recent build? (crash-stats isn't showing me any)
Flags: needinfo?(ryanvm)
Ah dammit, I could have sworn I was looking at the buildids on crash-stats but indeed there don't seem to be any newer than 20170217030229. Sorry for the false alarm.
