--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I don't see a problem here, and I don't see why we should change anything when
the code works fine.

During constant evaluation, if nothing gets destroyed then the destructor is
not needed. So it's irrelevant whether it's constexpr or not.
