Thanks Jason,
So when I add at the end of CubitFile.hpp

Index: CubitFile.hpp

 } // namespace NCubitFile

it compiles and runs "fine". If I do only char[4], it crashes early, and when I do
char[8], it crashes more spectacularly, with a stack corruption.

What would be the best solution? (maybe I should just ifdef-it for 32 bits?)

Thanks,
