That's actually a library issue, not a compiler issue. You're expecting C++14's SFINAE-friendly result_of, but you're getting C++11's SFINAE-hostile result_of. (That's in addition to the fact that our result_of/<functional> implementation has numerous bugs with respect to C++11.)

Unfortunately, I won't be able to fix this in 2013 RTM. result_of needs to be thoroughly overhauled, but I'm not allowed to make such a major change at this point. I should be able to do this for the next major version, though.

As an aside, why is Boost using std::result_of anyways? You've got Eric Niebler and his SFINAE-friendly boost::result_of, you know. :->
