Clang is actually behaving correctly here. The friend struct template
declaration here:

namespace detail {
    template <class T>
    struct Info {
        template <class X> friend struct Test;    
    protected:
        Info(int) {}
    };
}

actually makes the struct template "detail::Test" a friend, because friend
declarations refer to the innermost enclosing namespace. 

The right way to do this would be:


template <class T> struct Test;

namespace detail {
    template <class T>
    struct Info {
        template <class X> friend struct ::Test;    
    protected:
        Info(int) {}
    };
}
