Illegal VIRDEF fixup index in Module XYZ

[I Own The Letter O]

Hi,

I'm quite new to the whole world of Cpp so the above fatal error is
very perplexing. I have a very simple program at the moment and I get
the above error. I have searched on the Internet and only got six
hits, all in foreign languages. I have searched the newsgroups and it
turns up a couple of times but no real solution is given. Can anybody
help/explain what I've done wrong and how to fix it?

Regards,
