Hi,

Boost.Thread move semantic emulation up to 1.49 has many problems. I 
have reworked the move semantic interfaces adapting them to Boost.Move 
in trunk (I hope it will be released for 1.50).

If you can not use the trunk,

have you tried with

boost::unique_future<T> f() {
   /// x
   return boost::detail::thread_move_t<T>(x);
}

Best,
Vicente
