--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Reduced test-case:
namespace std {
template <typename> struct common_type;
template <typename... _Tp>
using common_type_t = typename common_type<_Tp...>::type;
} // namespace std
template <typename T, int> class vec {
public:
vec(T, T, T);
};
template <typename... Args>
vec() -> vec<std::common_type_t<Args...>, sizeof...(Args)>;
template <typename T> using vec3 = vec<T, 3>;
void lala() { vec3(1, 2, 3); }
started with r10-5020-g1a291106384cabc7.
