Unsurprisingly ubsan doesn't like referencing a null pointer.With this change __array_traits::_S_ref is only used to access an element, which is invalid for std::array<T, 0> anyway.
Should return *static_cast<_Tp*>(nullptr); be replaced with __builtin_unreachable();then? It seems strange to keep an implementation that is never supposed to be used.
