make_ready_future<void> bug

[dvvn]

Used boost version 1.76.0

next code from future.hpp, line 4388 promise\<void> have no emplace method

 // variadic overload
#if ! defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES)
  template <class T, class ...Args>
  BOOST_THREAD_FUTURE<T> make_ready_future(Args&&... args)
  {
    promise<T> p;
    p.emplace(forward<Args>(args)...);
    return p.get_future();

  }
#endif

header contains correct function for promise\<void>, but compiler always select variadic-templated method instead of normal
