Comment on UndefinedBehaviorSanitizer's Unexpected Behaviorparent

The author admits to not being a C undefined behavior expert

At this stage, I would seriously doubt the credentials of anyone who claims to be a C undefined behaviour expert. Saying "I'm not a C UB expert" is just a realistic acknowledgement that UB is hard and we will get it wrong at some point without realising. The approach of having an automated tool tell you when UB is present is very sensible.
