[Boost-users] Problem with boost archive. Cannot solve in any way.

Hello. I have this code, which throws an exception and I cannot find in any way why. It throws an invalid_signature exception. I'm sure that the serialized data where it comes this data from is correct. The code: std::string data_bytes(std::get<1>(*datos).begin(), std::get<1>(*datos).end()); std::istringstream stream(data_bytes); MensajeRed msg; //FIXME: This constructor throws boost::archive::binary_iarchive archive(stream); archive >> msg; Throws in the constructor of boost::binary_iarchive. Thanks in advance.
