--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
It has nothing to do with the auto return (and so probably nothing to do with
64194).

Reduced:

template<typename... T> struct tuple { };

template<typename F, typename Tuple> auto apply(F&&, Tuple&&) { }

template <typename... Types> void add1(const Types...) { }

int main() {
  apply(add1<int,int>, tuple<int, int>());
}
