--- Comment #2 from Paul Preney <paul at preney dot ca> ---
It seems to the similar/equivalent. That said, clearly this is not a constexpr
issue (which bug 59296 does not demonstrate).

A concern of mine is that this appears to effectively, especially given the
immportance of using const in C++, render GCC's C++11 rvalue *this
implementation practically unusable in many classes until this is fixed.
