Description

The following code

#ifdef BOOST_THREAD_PROVIDES_EXECUTORS
  {
    try
    {
      boost::executor_adaptor<boost::thread_pool> ex(1);
      boost::future<int> f = boost::async(ex, &f0); // [HERE]
      boost::this_thread::sleep_for(ms(300));
      Clock::time_point t0 = Clock::now();
      BOOST_TEST(f.get() == 3);
      Clock::time_point t1 = Clock::now();
      BOOST_TEST(t1 - t0 < ms(300));
      std::cout << __FILE__ << "[" << __LINE__ << "] " << (t1 - t0).count() << std::endl;
    }
    catch (std::exception& ex)
    {
      std::cout << __FILE__ << "[" << __LINE__ << "]" << ex.what() << std::endl;
      BOOST_TEST(false && "exception thrown");
    }
    catch (...)
    {
      BOOST_TEST(false && "exception thrown");
    }
  }
#endif

generates this compile error in line [HERE].
