#9442: boost::asio::spawn does nothing when coroutines v2 are enabled

     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  asio
  Version:  Boost 1.55.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+----------------------------
 Following code works as expected (i.e. prints 'works'). However, it prints
 nothing if you uncomment lines that enable (or try to enable) use of
 coroutines v2 in spawn.

 {{{
 #include <iostream>
 #include <functional>
 //#define BOOST_COROUTINES_UNIDIRECT
 //#define BOOST_COROUTINES_V2
 #include <boost/asio.hpp>
 #include <boost/asio/spawn.hpp>

 void foo(boost::asio::yield_context ctx)
 {
     std::cout << "works!" << std::endl;
 }

 int main()
 {
     boost::asio::io_service srv;

     boost::asio::spawn(srv, std::bind(foo, std::placeholders::_1));
     srv.run();
 }
 }}}

 I am not sure if asio is intentionally not using new coroutines interface
 by default, but this seems pretty important thing going forward.
