This case fails:

struct base {
};

struct derived : base {
    derived(const base &state)
    : base{state} // Gcc, Clang, and EDG reject.
    {}
};

void f(base b) {
    derived d{b};

}

Should this be a separate bug? The call of the implicitly-defaulted
copy constructor fails using list-initialization, so this seems like
it should be part of the same PR.
