--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Reduced testcase:
template <typename> void foo ();
template <typename, typename> struct A;
template <typename T, typename U = decltype(foo<T>)> using B = U;
template <typename T> using C = B<T>;
template <typename T> A<C<T>,int> a;
-fconcepts isn't needed.
Started with r277281.
Can't reproduce with current trunk though, only r278068, so most likely dup of
PR92206.
