I compiled, linked and executed this exact program on my VC 7.1 setup.
I had no problems of any kind

Thanks for the help. The new code works.
For my application, I would like to use BOOST_CLASS_EXPORT_GUID to simplify
the registration process. Changing the demo code to use EXPORT causes it to
core dump. Perhaps I'm not using correctly... Again, help would be
appreciated.
