Can't reproduce with frame or slice threading or no threading. What
was the command-line?

Indicates maybe frame+slice, but that brings me to the point: why is
it crashing at all? Is it something that should be avoidable through
It seems I should just avoid running the slice-threading code in the
frame threading case.
