Hi Igor R, Thank you very much for your reply. Now I have got a resolution that moving the initialization of 2 variable objects (work_resolver_ , work_socket_) that you mentioned into start() function from the constructor.

boost::asio::io_service work_io_service_; <...>
Please, pay attention that member objects are initialized in the order of their definition. I.e., when you initialize work_resolver_ and work_socket_ you pass them uninitialized work_io_service_ as a parameter. _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
