So I suspect this is a bug in 'type_traits' library, but I'm not sure. Hopefully somebody else can confirm. (I'm sorry but I don't know to whom should I CC this post.)

I don't know why clang accepts your code though. Perhaps `boost::is_convertible` is conditionally compiled to some different implementations in Clang.

Thanks for the analysis.

My guess is that clang uses a different implementation of is_convertible.

Also, I guess this works in C++14 because std::is_convertible is used instead?
