1113776 - Crash/Hang running youtube's MSE tests

Status: RESOLVED DUPLICATE of bug 1114383

(Core :: Audio/Video, defect, P2)

Description

[cmtalbert]

= STR =
Open a tab to http://yt-dash-mse-test.commondatastorage.googleapis.com/
Click "Run All"

Expected
Test runs to completion with errors

Actual 
Test damages entire browser session and does not run to completion (might be intermittent)

So, I hit two strange behaviors one with E10s mode on and one with E10s mode off. Both were from clicking on the "run all" link on the page and both happened somewhere between the Buf/Unbuf test (number 40 something-ish) and the Frame Gaps test.

= E10S Enabled =
I crashed the content process. Here is the report: https://crash-stats.mozilla.com/report/index/f76c50ca-3cc9-442f-ba01-e0c302141219

= E10s Disabled =
It hung the entire browser. It seemed like it hung a rendering thread because I could do some things - like switch between windows, click the "new tab" button, but I couldn't type in the search or URL bar, I couldn't see the new tabs I created from clicking the button, but if I tried to drag the space where they would be, a thumbnail would appear showing the new tab page. And, when I restored after killing the task, it restored with several new tab pages there.

Further attempts to repro this saw the bug become intermittent, and then trying to load the page results in an error: "XML has no style data". So I don't know if this is a case of google updating the page while I was running it or the page damaging itself while running. I tried loading in different browsers and am now constantly getting the XML error, so I think there has been a server update during my testing this morning.

Sorry for the crappy report, wish I could pinpoint what is happening here.

http://yt-dash-mse-test.commondatastorage.googleapis.com/ is XML content for me.
Where is your "Run All" link ?

Could you please confirm which URL you used ? thank you

This looks like memory corruption caused by bug 1114383. Please reopen if you hit this again.
