That hasn't happened before so it would be good to know which latest landing has caused this regression.

That's true of every single intermittent-failure - with one failure, we know the odds of hitting this are 1/∞, so we could find where it was introduced by retriggering ∞ times on every push between that one and the one where the peerconnection tests got turned on.
I haven't said now. But yes, if it doesn't reproduce yet we will have to wait.

Assigning to Adam as this seems like it may be related or the same as the other SIPCC startup race causing basicaudio failures

Comment 7

Just this morning, I found myself wondering why we're not seeing the race I describe in the third paragraph of Bug 823056 comment 34 being lost in other ways than the one that leaves CCApp spinning in depart. There should be variations on the corruption of the circular linked list.

This looks like one of the variations I would have expected to pop up.

I agree with Randell that this almost certainly has the same root cause as bug 823056. Because it has a different signature when the race is lost in this direction, I'll leave it open and mark it as depending on 823056 (rather than marking it a dupe). I think we can close them at the same time once the race is fixed.

Ed: The log in comment 5 isn't this problem; it's Bug 833557.

Sorry, must have been a misclick, the two bug suggestions are next to each other in TBPL's annotated summary.

As mentioned before, this is the same as bug 823056, which has been patched and landed on m-c. I'm closing this bug as a duplicate now.
