Hi

This is probably bug in my app, but I need an idea how to track it down.

Seen on MSVC8, XP

Occurs after io_service, which is processing many timers, sockets and posts 
in one thread is stopped from another thread. It is stopped fine, however it 
crashes on service object destruction at this line:

    // Delete the timer.
    void destroy()
    {
      destroy_func_(this); ////
    }

destroy_func_  is often 0xfeeefeee, but sometimes it is 0x0 or any other 
value.

Call stack is:

boost::asio::detail::timer_queue<boost::asio::time_traits<boost::posix_time::ptime> 
 >::timer_base::destroy()  Line 211 + 0xe bytes C++
boost::asio::detail::timer_queue<boost::asio::time_traits<boost::posix_time::ptime>

bytes C++
boost::asio::detail::service_registry::`scalar deleting destructor'()  +

Any ideas ?
