The `constexpr` in the main function is not necessary to produce the warning. 

The Function foo has to be constexpr. 'inline' or 'static' (before the
function) does not produce the warning.

Maybe `constexpr` functions have better optimization and in one of the
optimizations happens unwanted stuff.

I don't think it is an compile-time/run-time issue.
