13567,io_context ::run() doesn't return immediately on stopped io_context due to Windows implementation,cvzakharchenko@…,chris_kohlhoff,"This code hangs, when running on Windows:
{{{
    boost::asio::io_context context;                // 1
    boost::asio::post(context, []() { for (;;); }); // 2
    context.stop();                                 // 3
    context.run();                                  // hangs in a handler, posted in 2
}}}

[https://www.boost.org/doc/libs/1_67_0/doc/html/boost_asio/reference/io_context/stop.html io_context::stop] documentation says:

  Subsequent calls to run(), run_one(), poll() or poll_one() will return immediately until restart() is called.

Which is, judging by example above, isn't true. Same goes for [https://www.boost.org/doc/libs/1_67_0/doc/html/boost_asio/reference/io_context/stopped.html io_context::stopped]:
  When an io_context object is stopped, calls to run(), run_one(), poll() or poll_one() will return immediately without invoking any handlers.
and code example below:
{{{
    boost::asio::io_context context;                // 1
    boost::asio::post(context, []() { for (;;); }); // 2
    context.stop();                                 // 3
    if (context.stopped())
    {
        context.run();                              // hangs in a handler, posted in 2
    }
}}}

When running on Linux, same code fully complies the documentation and doesn't invoke any handlers in examples provided.",Bugs,new,To Be Determined,asio,Boost 1.67.0,Problem,,"windows, io_context, stop, stopped",
