G++ issues the same diagnostic message for the following example:
template<class>
class base {};
class derived : public base<derived>
{
// error: specialization of 'base<derived>' after instantiation
template<class>
friend class base<derived>;
};
It seems that in the original example g++ incorrectly treats the
injected-class-name ::base<derived>::base as template specialization
base<derived>, while according to 14.6.1/1 it shall be refer to class template
base. Note that g++ does not issue an error in the following case:
template<class>
class base {};
class derived : public base<derived>
{
template<class>
friend class ::base;
};
int main() {}
