[boost] asio::demuxer at global scope dead-locks?

4 Sep 2005

      I tried modified the timer1.cpp a little:

#include <iostream>
#include <asio.hpp>

asio::demuxer d;

int main()
{
    asio::deadline_timer t(d, boost::posix_time::seconds(5));
    t.wait();

    std::cout << "Hello, world!\n";

    return 0;
}

by moving the demuxer object to global scope.
I have to be honest, I am not through with the documentation yet,
but also I did not find a bold mark which prohibits such
use.

At least the program seems to never end, it seems to hang somewhere
in the library clean up code? I can see it waiting for a thread to stop:
// Wait for the thread to exit.
  void join()
  {
    ::WaitForSingleObject(thread_, INFINITE);
  }

But this never happens.

Is it true indeed, that demuxer s must not be at global scope?
