@danilaml : What happened with the miscompiles you saw?

The reason I'm asking is that I've bisected a problem we've seen for our downstream target to this patch. I don't know yet if it's due to a broken input program, miscompile, or what, but when I saw the comment above about miscompiles I wondered what happened with that.
