Hello,

Running mysqlpp 2.1.1 on Windows XP and 5.0 mysql.
 
Been trying tracking down what appears to be a leak. A
wee bit bizarre.

I have a column in a mysql database called messageData
is a VARCHAR(4096).

I have the following code extract:

mysqlpp::Query query = _con.query();
mysqlpp::ResUse res = query.use();

mysqlpp::Row row;
try {

      if (res)
      {
         while(row=res,fetch_row())
         {
         }
      }
}
catch (exception & er)
{
   cout << "Failed Dude! " << endl;
   return 0;
}

Seems straightforward. It always ends up going to
"Failed Dude".
It then pops a leak. I commented out the above code
and it no longer leaks.

Can somebody be so kind to enlighten me on what I
assume to be misuse of the above so I can avoid the
leak.

Thanks,
Garyc
