You only get a "different result" when an undefined behavior happens,
thus it **is** a valid point to say there is no wrong-code issue.

It's a real bug. There are many PRs on bugzilla.

You may argue it's a missed-optimization, but we were discussing about
wrong-code or not.

Nobody in this thread has been thinking it's wrong code.

When there is no overflow, it's missed optimization. When there is an overflow, I don't care.

Do you agree?
