I tried to post this problem in the asio mailing list but I hadn't any feedback, so I'm reporting it here with the hope that someone can help me. I have a "stack overflow" problem with the following code (using boost 1.36): void test_handshake(const std::string &host, const std::string &cert) { boost::asio::io_service service; boost::asio::ssl::context sslContext(service, boost::asio::ssl::context::sslv23); sslContext.set_verify_mode(boost::asio::ssl::context::verify_peer); sslContext.load_verify_file(cert); boost::asio::ip::tcp::resolver resolver(service); boost::asio::ip::tcp::resolver::iterator endpoint_iterator = resolver.resolve(boost::asio::ip::tcp::resolver::query(host, "443")); boost::asio::ip::tcp::resolver::iterator end; boost::asio::ssl::stream<boost::asio::ip::tcp::socket> sslSocket(service, sslContext); boost::system::error_code error = boost::asio::error::host_not_found; while(error && endpoint_iterator != end) { sslSocket.next_layer().close(); sslSocket.next_layer().connect(*endpoint_iterator++, error); } if(error) throw boost::system::system_error(error); sslSocket.handshake(boost::asio::ssl::stream_base::client); // bla bla } When I call this function with a valid certificate for the host I have no problems, but when I pass a "custom" cerificate (not valid for the host specified) it results in a stack overflow error instead of throwing an exception as I expected... This example works: test_handshake("sourceforge.net", "cacerts.pem"); // grab cacerts.pem from here for example: http://www.cs.fsu.edu/~engelen/soapcacerts.html This causes, as I said, a stack overflow instead of an exception: test_handshake("sourceforge.net", "ca.pem"); // ca.pem was taken from the asio examples Plz help P.S.: is anyone using asio with ssl? It's very strange that nobody has reported this problem... _________________________________________________________________ Cerchi un locale per la serata? Chiedilo a Live Maps! http://maps.live.it/
