Note that this patch is dependent on http://reviews.llvm.org/D19674 which was reverted at http://reviews.llvm.org/rL268577.

I've been trying to locate the msan failure that caused the revert, but no luck so far: I don't see any problems running under valgrind. Trying to repro using msan directly now. If anyone can help spot the bug, I'd appreciate it.
