Makoto,

This looks like it is crashing in the mac bits. Want to take a look?

Comment 3

[Makoto Kato [:m_kato]]

I take this.  Also, this reproduces on Windows too.

Comment 4

[Makoto Kato [:m_kato]]

This issue seems to be e10s only

Comment 5

[Makoto Kato [:m_kato]]

Oops, mac may not e10s only.   I should test it on mac.

Bughunter reproduced this with Nightly using the attachment on OS X 10.8, 10.9. Haven't seen it yet on other OSs.

Part 1. Check mTask since end event is posted asynchronized

The callback into nsSpeechTask will be released by end event.  But since end event is posted asynchronized, when calling pause and resume, web content doesn't receive end event yet.   So we should check mTask on Windows and cocoa backend.

Part 2. Add crashtest

Part 2 test will causes leak on Linux build.  So mark as obsolete.

When adding crashtest, I found memory leak on linux build.  mTask has to release when speaking is end.

Part 2. Add crashtest

This test doesn't work on Android, gtkWidget and B2G, so I add skip list.  Android has no backend, and Linux and B2G doesn't have speech library on our test environment.

Backed out just the crashtest in https://hg.mozilla.org/integration/mozilla-inbound/rev/a5fa1e187b98

Apparently has a race that you lose when the test machine is too fast: only on Windows 7 (among the runs that happened while it was in the tree, anyway), more commonly on opt and PGO than on debug, which is why I think you're losing when it's running quicker, as often as not you got https://treeherder.mozilla.org/logviewer.html#?job_id=18472557&repo=mozilla-inbound

Humm, it isn't opt issue, and it is VM issue.  Cancel spends more time (1s?), but evne if opt build, test is successful.  Maybe, failed VM doesn't have any voice of speech engine or configuration.

So I will think another hack to run this test.

Encountered this crash on Firefox 45 beta 1 on Mac OS X 10.9.5.
I set up media.webspeech.synth.enabled to true in order to test Text to Speech feature.

STR:
On http://mdn.github.io/web-speech-api/speak-easy-synthesis/ or http://eeejay.github.io/webspeechdemos/ test pages, after entering some text and selecting a voice, start the speech and then select another voice. Refresh the page several times if needed.

crashtest v2

test only on OSX.  Some Win7 VM is always failure due to unknown reason.　(ex. t-w732-ix-036 is always failure, but t-w732-ix-036 is successful).

Also, this is passed by https://treeherder.mozilla.org/#/jobs?repo=try&revision=06749a4a2afb

Humm, this is another crash.  Could you file a new bug for Nightly?

If it is a non intermittent failure, shouldn't it be possible to debug and figure out why it doesn't pass in windows?

I couldn't reproduce it on latest Nightly 47.0a1 and latest Aurora 46.0a2 2016-02-02.
This only happens on Firefox 45 Beta 1 & 2 when enabling the webspeech feature.
Should I file it against Beta considering it won't be enabled by default in this version?

I cannot reproduce on my environment.  But this occurs on our test infra for Win7 opt only.  I think that SAPI's Speak method spends more times to start it, then this occur.

This feature won't turn on 45.  So it is unnecessary.

No crash, so I close this.  For OSX 10.6, we will continue by bug 1252673.
