It wasn't just something weird on your system, it's fundamental: you 
can't use a debug MySQL++ DLL from a release executable.  (Dunno if the 
converse is true as well.)  Guaranteed havoc results if you try.  I can 
only guess why this is, but since the fix is so simple, I'm not 
motivated to find out for sure.
