--- Comment #1 from David Stone <david at doublewise dot net> ---
I have simplified the test case further:


struct base {};

struct derived :  base {
        constexpr derived():
                base{},
                m_value(0) {
        }
        int m_value;
};

constexpr int by_ref(derived && value) {
        return value.m_value;
}

constexpr int value = by_ref(derived{});
