824711 - Crash [@ mozilla::DataChannelConnection::Close]

Status: RESOLVED DUPLICATE of bug 805251

(Core :: WebRTC, defect, P1)

Description

[Florian Quèze [:florian]]

When I restart Nightly (using restartless restart https://addons.mozilla.org/fr/firefox/addon/restartless-restart/) during a webrtc call made through the SocialAPI demo (https://github.com/mozilla/socialapi-demo), Nightly usually freezes, but sometimes it crashes instead.

The crash stacks I got today are:

I remember seeing this before, and I thought I had already filed this, but I can't find the bug again, so I prefer risking filing a dupe than not filing the bug at all.

Marking as security is slightly aggressive, as the use-case was in shutdown - but this might be possible to invoke when cleaning up datachannels; we won't know until I diagnose, so it's safer to close access for now.

Yes, that was bug 805251 which has been duped against bug 807929. The latter was fixed on Nov 2nd, so we should reopen bug 805251 and dupe this against it.
