1286447 - video playback crashes firefox in e10s window

Status: RESOLVED DUPLICATE of bug 1286527

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

Description

[Cyrus Harmon]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:50.0) Gecko/20100101 Firefox/50.0
Build ID: 20160708230936

Steps to reproduce:

Going to any page with video on it (follow any link off of the youtube.com home page, for instance)


Actual results:

I get the message "Bad news first: This tab has crashed"


Expected results:

The video should have played and the tab should not have crashed. Note that if I try this in a non-e10s window, the video plays as expected.

WFM with FF50 on Win7. Do you have crash reports (bp-...) in about:crashes?

Comment 2

[Cyrus Harmon]

I don't see the crash showing up in about:crashes. Could that be because firefox is picking up the fact that the tab has crashed and is not reporting it to the crashreporter?

Here's a stack trace from visiting youtube.com:

Comment 3

[:Gijs (he/him)]

Paul/Julian, in response to your m.d.platform posts, I assume you're the people to ping about this Linux sandbox violation crash. Is there enough detail here for you to work with and/or can you request whatever you need from the reporter? :-)

Comment 4

[Julian Hector [:tedd] [:jhector]]

Yes, we are the correct people to ping about this.

Looking at the backtrace in Comment 2, it shows that sys_semop is called which isn't whitelisted yet.
Bug 1286527 was filed for this and the patch is currently on inbound. Expect this to be fixed soon.
