Trying to compile

template<class T>
struct testclass
{
    template<int I>
    class inner {};
    template<int I>
    void f(inner<I> ) {}
};

template <typename T, int I> using inner = testclass<T>::inner<I>;

int main()
{
    testclass<bool> test;
    test.f(inner<bool,3>());
    return 0;
}

I get the following crash:
