Hi Steven, I'm looking for a crash I get in my own code with g++4.8.1 (4.5 - 4.7 are ok). Maybe you can help me: - there is a copy_constructible concept, but no moveable. Is it enough to add one on the same model? It looks like you std::forward so I'd say yes. Correct? template<class T = _self>
struct move_constructible :
::boost::mpl::vector<constructible<T(T&&)>, destructible<T> >
{};
I believe that this should work. However, overloading const T& and T&& only works with clang. (It might work with gcc-4.8, if I enable it. When I wrote the code I only had gcc-4.7.).
I'm willing to try it out as I have a gcc-4.8.1 at hand. How do I do this?
- If I std::move a copy_constructible any type by accident, what do I get? A copy? A crash?
It should do a copy. I tried hard to make overload resolution behave the same as it would with real references.

Hmmm ok then I need to have a closer look at my crash. Thanks, Christophe
