--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
Changing R42c to be a bool rather than a concept causes GCC to catch the
failure ...
That is:
```
template <class T> struct A { static const int x = 42; };
template <class Ta> concept A42 = A<Ta>::x == 42;
template <class Tv> concept Void = __is_same_as(Tv, void);
template <class Tb, class Ub> concept A42b = Void<Tb> || A42<Ub>;
template <class Tc> bool R42c = A42b<Tc, Tc&>;
static_assert (R42c<void>);
```
