Yes. I'm attaching a patch (very much experimental - it might
introduce new problems rather than fix old ones) that might also be
worth testing on top of 3.19.

Hey, so far nobody else has been able to pin this down either. It
seems to be very timing-specific, and it's possible (even likely,
considering DaveJ's adventures) that while you cannot trigger it with
3.16.7, it might be lurking there too, just not with the kind of
timing that can trigger it on your machine. Which would explain the
bisection trouble.

It would have been wonderful if somebody had been able to really
reproduce it truly reliably, but it seems to be very slippery.
