1476110 - WebRTC audio call crashes tab

Status: RESOLVED DUPLICATE of bug 1475431

(Core :: WebRTC: Audio/Video, defect, P1)

Description

[Mike Tomko [:kibaurufu]]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:63.0) Gecko/20100101 Firefox/63.0
Build ID: 20180716100102

Steps to reproduce:

Bug first appeared in nightly builds around July 12th.
I can reproduce this in Google Hangouts for Web and Discord for Web, but it's easiest to reproduce with the webRTC demo found here https://webrtc.github.io/samples/src/content/peerconnection/audio/


Steps to Reproduce:
1. Visit WebRTC peer connection audio demo page
2. Click "call"
3. Allow microphone access for site


* Running Windows 7 x64 on an AMD FX-8350 system, with 32GB of DDR3 ram, and an AMD R9 290X graphics card.
* Reproducible on Windows 10
* Unable to reproduce on OS X 10.13.6 (High Sierra)


Actual results:

Tab crashes almost immediately after allowing microphone access.


Expected results:

Tab should not have crashed, and a WebRTC audio call should have been established and transmitting audio.


(Apologies if there is already a bug for this, but I could not for the life of me come up with the right search terms to find it)

Paul, do you think it can be responsible for this crash?

Is there somewhere besides "about:crashes" that I can find tab crash reports? Because unfortunately, "about:crashes" does not have any crash reports (submitted or not) for the tab crashes.

Mike, this is going to be fixed soon, and is related to a compiler change on our end. The patch is already written.

Thanks for the report and sorry for the trouble !
