Predator did not generate any regression range or suspect Cl.

Using code search suspecting below change could be a possible culprit which could have resulted in this crash:

I'm pretty sure this isn't related to my change (but I could be wrong!)

I thinnk this is the same underlying cause as  issue 731568 , which just fix for min_playback_rate_, which is the same areas as this repro case is pointing to.
