I'm having endless trouble trying to get a version of Clang up and running here (on Windows), as is customary.
I got the latest SVN Clang running, but now the test doesn't fail. Go figure. They must've fixed something.
I can reproduce it locally with clang 3.4. Shows only with -std=c++11 - stdlib=libc++. Trying to dig further.
Ok, here's the thing. libc++ only implements std::iterator_traits for class- type iterators if they have nested iterator_category typedef, and this typedef is one of the std:: iterator categories. Otherwise std::iterator_traits is empty. Replacing struct C { }; with typedef std::random_access_iterator_tag C; fixes the compilation for me.
