I've tried this out on my build test box in the past, but ran into some problems. In particular I ended up disabling -fsanitize=signed-integer-overflow and -fsanitize=object-size and later reverting the whole thing, but don't remember exactly why (possibly I was hitting internal compiler errors?).'
Let me re-enable it with your patch locally and report back with whatever build problems I run into.
