Mysql connector/c++ glibc detected invalid pointer

[Julien Martin]

Hello,
I am trying to run the following code:

 try {

        sql::Driver *driver;
        sql::Connection *con;
        sql::Statement *stmt;
        sql::ResultSet *res;

        driver = get_driver_instance();
        con = driver->connect("tcp://localhost:3306", "root", "root");
        con->setSchema("`hull-db`");

        stmt = con->createStatement();
        res = stmt->executeQuery("SELECT * FROM chapitre");

        while (res->next()) {
            cout << "num" << res->getInt("numero_chapitre");
            cout << "titre" << res->getString("titre_chapitre");
        }

        delete res;
        delete stmt;
        delete con;
       

    } catch (sql::SQLException &e) {
        cout << "ERR: " << e.what();
        cout << "MySQL error code: " << e.getErrorCode();
        cout << "SQLState: " << e.getSQLState();

    }

And I get the following error:
