The timeline is not right. This crash was reported in late 2016. That bug was closed in 2014. Sometimes frames get omitted from the stack trace; likely the crash is really inside mediaPlayerDidRemoveAudioTrack. The MediaPlayerClient is surely HTMLMediaElement.

I assume the crash must have been happening here:

void HTMLMediaElement::removeAudioTrack(AudioTrack& track)
    m_audioTracks->remove(track); // <---

But I agree the current code does not match up. I'm not sure when it changed; trac doesn't allow blaming HTMLMediaElement because it is too big, and GitHub just times out.

You are the assignee for the bug.
