Well... To know where this thing was coming from, i just started to comment out each line of code and tested what was happenning. I finally commented out all the code and the error was still there. Then figured out that the error is appearing as soon as my code includes: #include I moved it in different .h files and the effect was the same evenif i am not using no more anything with ssl. Does it help someone to explain? Thanks Sunsawe wrote:

Hi,I'm new to boost and asio. I'm trying to use the ssl support of asio in a simple client.This is the code that i'm using to connect to the server: boost::asio::io_service io_service; boost::asio::ssl::context * ctx; boost::asio::ssl::streamboost::asio::ip::tcp::socket * socket; boost::asio::error Error; boost::asio::ip::tcp::resolver resolver(io_service); boost::asio::ip::tcp::resolver::query query(boost::asio::ip::tcp::v4(),hostname,port ); boost::asio::ip::tcp::resolver::iterator endpoint_iterator = resolver.resolve(query,boost::asio::assign_error(Error)); boost::asio::ip::tcp::resolver::iterator end; if(Error) return false; ctx = new boost::asio::ssl::context(io_service, boost::asio::ssl::context::sslv23); boost::asio::ip::tcp::endpoint endpoint = *endpoint_iterator; socket = new boost::asio::ssl::streamboost::asio::ip::tcp::socket(io_service,*ctx); Error = boost::asio::error::host_not_found; while (Error && endpoint_iterator != end) { socket->lowest_layer().close(); socket->lowest_layer().connect(endpoint,boost::asio::assign_error(Error)); } if (Error) return false; socket->handshake(boost::asio::ssl::stream_base::client,boost::asio::assign_error(Error)); if (Error) return false; else return true;That compiles fine but at run time i have this assertion exception:Assertion failed!Program:... //it is written like thatFile: (PATH)\boost-1_33_1\...\shared_ptr.hLine: 253Expression: px != 0I'm using vs2005. i can't see what is happening because evenif i'm using the "Step Into new Instance" mode to run the program in debug mode, the exception is fired before any step.
