I am able to reproduce this as well, when doing

#include <boost/thread/mutex.hpp>

within a .cpp that uses boost::lock_guard<boost::mutex>

under Visual Studio 2015 Update 2 RTM

I hit the same bug.

The workaround is to try including <boost/thread> before <thread>.

This file has changed a lot since Boost.Thread has moved to Boost.WinApi.

Please, let me know if those changes solve the issue and we can close it.
