Subject: [boost] Asio and SSL problem

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...
