--- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> ---
At present, 4.9 is conforming to C++11 and 4.8 is not. In general this is
tracked in http://cplusplus.github.io/LWG/lwg-active.html#2193 and as you can
see there are clear issues with the separate non-explicit default constructor
vs explicit instantiations.
