~QOCIResult: unable to free statement handle

Question

Good morning
I have a problem with an application. First of all I use oracle db 10 and qt 4.6 with c++ and I have written this code:
void DBConnector::releaseConnection(const dbConnection& dbc)
        QMutexLocker locker(&mt_connections);
        QString conn_id = dbc.getId();    //here I obtain my connection name
        cout << "Release Connection: " << qPrintable(conn_id) << endl;
        QSqlDatabase myDB = QSqlDatabase::database( conn_id );
        myDB.close();
        QSqlDatabase::removeDatabase( conn_id );
}The code compiles and works but it returns a warning: ~QOCIResult: unable to free statement handle
So I've lost two days to understand where the problem is but I wasn't able to find a solution. I've also opened the qsql_oci.cpp file and I've found this:
QOCIResult::~QOCIResult()
    if (d->sql) {
        int r = OCIHandleFree(d->sql, OCI_HTYPE_STMT);
        if (r != 0)
            qWarning("~QOCIResult: unable to free statement handle");
    delete d;
}I think the problem is in the OCIHandleFree method. Do you know how to solve it? Is this a bug between qt and oracle?
Thanks

If there's a problem between a 3rd party product and Oracle,you better consult the 3rd party (because the 3rd party vendor prepares the API).
