Not really. Since they're relying on more or less undefined things
(such as the contents of the stack area next to some parameter), the
behaviour can easily be different on different platforms. It could
even be different on the same platform (e.g. in Dos when loaded at
different addresses -- or under a debugger). That's the kind of bugs
that's hard to track.
