PR c++/71515 - typename in partial specialization
* pt.c (resolve_typename_type): Try to avoid calling
currently_open_class.
Testcase:
template <bool> struct A;
template <bool _Cond> using enable_if_t = typename A<_Cond>::type;
template <typename, int, typename, typename> struct B;
template <int> struct C;
template <typename> struct D;
template <typename Scalar_, int Size_, typename Derived>
struct B<Scalar_, Size_, Derived, enable_if_t<C<Size_>::peel>> {
using Base = D<Scalar_>;
// typedef D<Scalar_> Base; // OK
using typename Base::Scalar;
Scalar a;
};
See: PR69481 for a similar issue.
