[Nico Weber via Phabricator via cfe-commits]

We bisected a test failure to this (https://bugs.chromium.org/p/angleproject/issues/detail?id=5500#c17). Can you expand a bit on what this patch means in practice? I'm guessing it makes UB in C++ code have bad effects more often? If so, what type of UB?
