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?

(In reply to Andrew Overholt [:overholt] from comment #5) > 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...
Flags: needinfo?(jyavenard)
Assignee: nobody → jyavenard
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.

:gbrown, could you look over my retriggers?
Flags: needinfo?(gbrown)
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?
quick and dirty fix... no idea on how that pointer could be null in the first place.

(In reply to Joel Maher ( :jmaher) from comment #10) > :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.
Flags: needinfo?(gbrown)
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. (https://hg.mozilla.org/try/file/28072c2a07ae/dom/media/webspeech/synth/nsSpeechTask.cpp#l789)
"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.
