plz help me.. there is a memory leak..

I am making some server program that insert data to mysql 5.0.6
And I am using mysql++-2.0.7. 
 
But there is a memory leak, so let me know how can I avoid this problem.
========================================================================================================
mysqlpp::Query query = g_dbcon.query();
query << "insert into table_name \
              
(column_0,column_1,column_2,column_3,column_4,column_5,column_6,column_7,column_8,column_9)
 \
              values(%0q, %1q, %2q, %3q, %4q, %5q, %6q, %7q, %8q, %9q)";
query.parse();
unsigned int i; 
for(i=0;i<receivedVector.size();i++) //receivedVector is Vector that store data 
to insert
{
    templateQuery.def[i] = receivedVector.at(i);
}
//until this, there is no memory leak
query.execute();    // <-------------------after here, this program's memory 
increasing
//query.execute("a","b","c"); // but if i insert data like this, there is no 
memory leak..
