should be: m_timer.async_wait(boost::bind(&IntervalEvent::handler, this, _1));
or:
m_timer.async_wait(boost::bind(&IntervalEvent::handler, this,
boost::asio::placeholders::error));

> Â Â Â  void handler(boost::system::error_code& error)

should be: void handler(cosnt boost::system::error_code& error)

On destruction, the timer cancels itself anyway.

By the way, you access the timers both from main() and from another
thread - which is illegal, since the asio objects are not thread-safe
(except for io_service).
