when i run the project i got

Unhandled exception at 0x00c55c8c in AccountServer.exe: 0xC0000005: Access violation reading location 0xfeeeff02.

and the call stack here

>

AccountServer.exe!boost::asio::detail::win_iocp_io_service::register_handle(void * handle, boost::system::error_code & ec)  Line 135 + 0x9 bytes	C++

so what's wrong here?!!

I've just started playing with boost and have implemented both the async server and client sides. One thing that I see wrong is the declaration of io_service inside of start_accept(). The io_service must exist outside start_accept so that you can eventually call io_service.run() and actually perform the accept().
