Running the following code:

typedef int my_int;

template <class T>
class my_type{
    public:
        T member;
        my_type(T t): member(t) {};
};

int main(){
    my_type<my_int> mt(0);
    return mt.member;
}

and trying to complete "print my_type<int>::my" the line gets replaced by

(gdb) print my_type<int>::_type<int>

And if it can keep going indefinitely:

(gdb) print my_type<int>::my_type<int>::my_type<int>::my_type<int>::_type<int>
