Aaron, can you please help with investigation here as bug 805591 is the suspected bug ?
Assignee: nobody → aklotz
Keywords: qawanted
Unfortunately there's no smoking gun in this call stack. The Plugin Hang UI changes touched mozilla::plugins::PluginModuleParent but did not touch any of the code shown in this stack.

If bug 805591 is indeed the cause, then it has induced some kind of side effect into the rest of the plugin code.

I'm also curious about bug 828034 and whether it is a different symptom of the same problem.
In case it's not clear from the code, this is very likely to be a case where PluginInstanceParent::PluginWindowHookProc is being called on an already-deleted PluginInstanceParent. This is also almost certainly the cause of bug 828034, which regressed in the same timeframe.

The most likely reason is that when a hang occurs and the plugin is destroyed, PluginInstanceParent::ActorDestroy is not being called, or is being called with a `why` other than `AbnormalShutdown`. This means that PluginInstanceParent::UnsubclassPluginWindow is not being called and the wndproc is left stale.
Blocks: 805591
Priority: -- → P1
When the plugin is destroyed, the Plugin Hang UI is posting a CleanupFromTimeout task to the main thread's MessageLoop. CleanupFromTimeout ends up destroying the PluginModuleParent actor and its subtree with AbnormalShutdown as the reason.

I'm wondering if there are events in the message loop that have been enqueued ahead of the CleanupFromTimeout task.
This patch fixes some synchronization problems that could cause spurious events and/or bad data to be sent between parent and child processes. I have no evidence that this is causing the crash, but this patch will either rule itself out as the problem or fix the problem.
Attachment #703157 - Flags: review?(netzen)
Can someone please attach some STR ? Even if they are not always crashing this.

As I know UserCallWinProcCheckWow means that a window procedure registered during the window creation is trying to process a message. It helps a lot if someone can find some STR.
There are only two comments:
"there is a script or something weird that always fails" (translated by Google)
"Everything keeps freezing and then crashes. it usually happens while I'm rendering something on photoshop."
If it happens while using Photoshop, mabye there can be a photoshop dll file that makes UserCallWinProcCheckWow to not work as expected. I'll try some tests and I will be back with results soon.

Try push with this patch:

Keywords: checkin-needed
Whiteboard: [leave open]
I've tried to reproduce the crashes on both latest Nightly and Aurora, with intense stress testing, but without any luck.

I've also tried to lower dom.ipc.plugins.hangUITimeoutSecs so that the Plugin Hang UI triggers more easily, but still no Firefox crash.

My attempts were with multiple tabs and multiple windows, all with Flash content, both on Windows 7 and Windows 8.
The crash hasn't disappeared on Nightly with this patch, it's still happening in recent builds.
I expect the patch that is about to land in bug 828034 to clear this one up as well.

This crash signature is shared by many bugs so it's not worrisome as long as it's a low volume.
UserCallWinProcCheckWow can be a signature for all kinds of different things. The particular case is here is fixed.

There's one crash in 20.0b1, bp-e00e2eb6-c035-4a2a-b2cb-7334b2130228, but not related to this bug.
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0

I've tried to reproduce this issue as in comment 13 with FF 21 beta 7 (Build Id: 20130506154904) on Windows 7, but without any luck.

In Socorro, there are no new crashes with [@ UserCallWinProcCheckWow] signature on Firefox 21 beta builds. Marking firefox 21 flag as verified based on this.
