--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Confirmed, clang++ compiles it.  Reduced:

namespace std {
template <typename> bool is_same_v;
namespace __detail {
template <typename, typename _Up> concept __same_as = is_same_v<_Up>;
}
template <typename _Tp, typename _Up>
concept same_as = __detail::__same_as<_Up, _Tp>;
} // namespace std
void f(auto... args) {
  [](std::same_as<decltype(args)> auto) {};
}
int main() { f(); }
