[boost] [move] [ thread] ambiguous call to overloaded function

Hello, Did anyone experience the following Revision 70494 tested on msvc2010 with headers the following headers: [code] #include< boost/thread.hpp> #include < boost/move.hpp > ... X x; boost::packaged_task<string_ptr_type> pt(boost::bind(&X::foo, boost::ref(x))); boost::unique_future<string_ptr_type> fs = pt.get_future(); boost::thread task(boost::move(pt)); fs.wait(); ... [code] outputs: .$(BOOST_ROOT)boost/move/move.hpp(304): could be 'boost::packaged_task<R> &boost::move<boost::packaged_task<R>>(T &)' or $(BOOST_ROOT)boost/thread/detail/move.hpp(44): or 'boost::detail::thread_move_t<T> boost::move<boost::packaged_task<R>>(T &)'
