--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Another testcase:
struct Elem {
    Elem* next_ = this;
};
constexpr Elem rs[1];
const void *p = rs[0].next_;

Which shows it is just an array issue; changing rs to be a non-array works that
is:

struct Elem {
    Elem* next_ = this;
};
constexpr Elem rs;
const void *p = rs.next_;
