this is occurring quite frequently since the first occurrence 2 days ago, doing some retriggers:
https://treeherder.mozilla.org/#/jobs?repo=autoland&filter-searchStr=android%20mda&tochange=0c0d4257e25432ae62dd66649cafc2bfcab75958&fromchange=1360cf36128d3d34284b700192e8c7055970f47a&selectedJob=101541528

I am not optimistic about finding a root cause with retriggers, but maybe we will see a better rate of failure.

:overholt, can you get someone to look into this?

:jya, I see via retriggers that bug 1363668 seems to be causing this crash, with 30 failures yesterday, this is on trend to be a top 5 intermittent failure, can you please take a look at this or consider backing out the patches from bug 1363668 if you don't have time in the next 2 business days?

Maybe Eitan can take a look (in case bug 1363668 isn't the cause)?

Haven't touched speech in a long time, so I am assuming the above prognosis is correct.

Note, our use of MSG is not really needed since we left B2G, and I think it should be removed. It's just not a high priority now (unless you say otherwise). This crash would go away if I purge our speech MSG support.

looking now..

I don't see how the code modified by bug 1363668 could be involved...

None of the code modified by bug 1363668 touch the code path used by this mochitest.

test_speech_simple.html only checks that some APIs exist. No media (audio or video) element is created.

So if that crashes it may be some other coincidence: corrupted compilation or what else.

Backing 1363668 would only get around a problem that would likely exist regardless...

so please don't back it out unless the problem is fully understood.file_speech_simple.html


the code of nsSpeechTask checks everywhere that mCallback is not nullptr except there... Sounds like there's a race somewhere where mCallback may not be set yet.

Well, there's no race where I thought. it's all main thread.

https://treeherder.mozilla.org/logviewer.html#?job_id=102486950&repo=try

we have mCallback that is null, yet nsSpeechTask::Setup was called where mCallback is set (and aCallback wasn't null)

memory corruption?

> :gbrown, could you look over my retriggers?

I believe this failure started earlier, on mozilla-inbound (but not on Android). The earliest I have found is:

https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&revision=a936e628dbb352550e1ad092db1474470215bda4

https://treeherder.mozilla.org/logviewer.html#?job_id=101449013&repo=mozilla-inbound

Since this happens infrequently on a lot of different platforms, it may be difficult to narrow down further.

This log:
https://treeherder.mozilla.org/logviewer.html#?job_id=102505667&repo=try

shows that nsSpeechTask::SetAudioOutputVolume prior nsSpeechTask::Setup was called, and as such, we have mCallback set to nullptr hence the null deref.

"outer-window-destroyed"

This appears to be related to changes in bug 1113086.

The nsSpeechTask is notified of a change when "outer-window-destroyed" occurs.

If this happens before nsSpeech::Setup got the chance to run, we will get a null deref.

So the behaviour is racy/unpredictable.

https://dxr.mozilla.org/mozilla-central/source/dom/audiochannel/AudioChannelService.cpp#443

The patch I proposed will get around the issue as when Setup hasn't been called yet, mCallback is null.

But there may be other cases where using the non-initialised nsSpeechTask could cause a problem, but I'm not familiar enough with this code.
