Exception thrown inside sql::Driver->connect

I am trying to connect to my MariaDB instance through C++ code. Here is the code which I got from here (obviously changed the ip and credentials) : https://mariadb.com/docs/clients/mariadb-connectors/connector-cpp/connect/#connector-cpp-connection-methods-driver

It throws the following exception at the "Establish Connection":

Exception thrown: read access violation. other.theString._Mypair._Myval2 was 0xFFFFFFFFFFFFFFEF.

sql::Properties properties({

return 0;
}??

I meet this error for 32 and 64 bits
