Because you've got a race condition between stream_handler (and its
private io_service) destruction, which occurs in the main thread, and
the internal io_service shut-down process, which occurs in the thread
that invokes io_service::run().
std::cout just take long enough to affect this race contdition.

To solve the problem, add thread.join() to the destructor.
