10447	io_service destructor hangs if serial_port read is queued, even if not running	Martinho Fernandes <martinho.fernandes@…>	chris_kohlhoff	"The following program does not terminate.

{{{
#include <boost/asio.hpp>

int main() {
    auto* ios = new boost::asio::io_service;
    auto* port = new boost::asio::serial_port(*ios);
    port->open(""COM6"");
    char c;
    boost::asio::async_read(*port, boost::asio::buffer(&c, 1), [](boost::system::error_code, int) {});

    delete ios;
}
}}}

Despite the fact that the io_service is not running, its destructor hangs if there is a pending async_read from a serial_port. If that read completes (by receiving one byte), the program terminates."	Bugs	new	To Be Determined	asio	Boost 1.55.0	Problem
