This revision now requires changes to proceed.

Removing noundef makes no sense to me, because the return value is noundef even under fno-exceptions. If we remove something, it should be the nonnull attribute, because that's what's actually being violated.

@ldionne Can you give us an ETA on D150610 <https://reviews.llvm.org/D150610> please? Do we need to introduce a workaround for this libcxx bug in clang, or do you plan to fix this in the near future?
