-fsanitize=undefined isn't an TBAA sanitizer, it can't detect aliasing
violations.
As for constexpr, you'd have to show us what exactly you've tested.
constexpr keyword on a function doesn't mean the function will be evaluated at
compile time, that happens only if it is called in constant expression.
