Alright, ignore my previous mail, I'm lagging behind it seems  ;-)

Could this be related to pointer trucation? The man page of dlopen tells
us that the return value is a pointer (hence the return value of
LoadLibrary has the same width). In your example you used an integer. Is
sizeof(Integer) = sizeof(Pointer) of your system?

If for example, you are missing the upper four bytes of the pointer, the
above message makes sense.
