Chrome hung upon joining Hangout

Project Member Reported by a...@chromium.org, Aug 15 2017 
Chrome Version: 62.0.3175.4
OS: Mac OS X 10.11.6 (15G1611)

No repro.

I joined a Hangout, and instantly Chrome hung. Attaching a symbolized sample, but it's

Hmm, looks like it hung while trying to malloc() which blocks the AudioUnit I/O thread and thus blocks the UI since we 1) must run on main thread and 2) that calls seems to block until outstanding AudioUnit I/O is complete.

Why we're hung in malloc I don't know though.

This might be related to  bug 756102 . In that bug I kernel panicked when entering a hangout, and in this one Chrome froze in some weird deep way.
