Compilers with segmented memory models can play all kind of tricks.
These under some configurations cut some corners for speed sake, even
pointers might not be capable of addressing more than a certain amount
of memory and adding a big offset to them results in pointer wrapping
instead of addressing of another segment.

I suppose that under this peculiar circumstances the compiler should
'warn real hard' but I have no first hand facts to show you.
