--- Comment #11 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Fixed for GCC 13.  The fix is probably unsuitable for backporting, and there
are workarounds anyway -- one workaround is to turn the problematic class into
a class template with an explicitly defaulted dtor, e.g. for the original
testcase do:

struct Base {
    constexpr virtual ~Base(){}
};

template<class=void>
struct Derived: Base {
  ~Derived() = default;
};

constexpr Derived<> d;
