Error with Object member variable of type std::string passed to Connect function.

Snippet below fails with error: 80040154 with a "Failed sz: Class ID String" error. I explored a bit but didn't find anything worth mentioning.

(**Object** passed into function)
string servername = ""; // connect to local server
servername = Object->OPCDA_servername; //server name holds "Matrikon.OPC.Simulation.1"
//servername = "Matrikon.OPC.Simulation.1";
client->Init();
if (!client->Connect(servername)) {}

Passing in the commented servername variable it works fine.
