New description:

 I am seeing an immediate crash as soon as I enable time stretch with
 passthrough enabled.  I was not seeing this on a build from 3/26.  Have
 not had a chance to try reverting the recent patches for fixing
 passthrough with time stretch to see if those are the cause.

 Am attaching my attempt at a backtrace.  Hopefully it got what was needed.
 Please let me know if you need anything else.
