You can report it as a bug to MS site or put it into VFP 8 wishes list document.

Well, I observing this thread from start and have one idea.
Why you store class in the separate EXE file? Is not it much easy to store it into the FXP file? I understand that this will require to turn the VCX into the PRG file that is a 5 minutes of work if you have no classes with objects containership tree deeper than 2 levels. However, you will have a benefit - FXP takes less space, and it cause no bugs like mentioned in this thread when you SET PROCEDURE it and than use CreateObject/AddObject instead of NewObject.

The explanation of this error is vague, but it's something with having set classlib to yourlibrary.vcx somewhere earlier in a project and then issue a NewObject function (or method) with the same classlib name.
