It turned out to be UB in our code as far as I can tell, see https://bugs.chromium.org/p/angleproject/issues/detail?id=5500#c36 and the follow-on.
(If this is known to trigger an existing bug more often, it might still be a good idea to undo it until that existing bug is fixed? But we're not affected by this existing bug as far as I can tell, so this is just a suggestion.)
