If you are using Visual Studio, the problem is some kind of memory leak 
having to do with the query object. I haven't narrowed it down, yet. I 
hope I have some time to look into deeper.

Look at this thread for more info on it: 
http://lists.mysql.com/plusplus/5743

Has anyone else had time to look into this memory leak? I barely have 
time to read these emails, these days. =)

BTW, Warren, you are doing a great job.
