--- Comment #1 from Patrick Palka <ppalka at gcc dot gnu.org> ---
We began rejecting this starting with r9-4879.
If we replace the explicit specialization of Inner<int>::~Inner with a generic
definition
struct Outer {
public:
template <typename T>
struct Inner { ~Inner(); };
};
template <class T>
Outer::Inner<T>::~Inner<T>() {}
Outer::Inner<int> x;
then we started to reject this version after r11-1350.
