It wouldn't work when this kind of loop is generated by macros/templates in some unreachable case left after const folding.
If it's truly unreachable then it's not likely to be a problem. If it is reachable and it's emerging from some macros and templates then I would be more inclined want a warning for it.
Yeah, but then you need compiler to somehow know if it's truly unreachable to know when to emit the warning and when to not do that.
If it's a warning and not an error then emit it whether it's unreachable or not
