--- Comment #2 from lizhenhuan1019 <lizhenhuan1019 at qq dot com> ---
Simplified the test case more:
int fun(int i)
{
    return 0;
}
template <typename F>
struct outer;
template <typename R, typename ...Args>
struct outer<R(Args...)>
{
    template <R(& f)(Args...)>
    struct callable
    {
    };
};
outer<int(int)>::callable<fun> f;//this line triggered the bug.
