rjmccall added a comment. When `__block` variables get moved to the heap, they're supposed to be moved if possible, not copied. It looks like PerformMoveOrCopyInitialization requires NRVO info to be passed in to ever do a move. Maybe it's being passed in wrong when building `__block` copy expressions in some situation.
Was there really not a test case covering those semantics?
