If that switch indeed depends on not faulting references to zero, it
probably isn't worth having.  Or if it's kept it needs a warning that
in many OS's it will fail.  The reason is that faulting on references
to zero is universally considered a Good Thing and many OS's go out of
their way to provide that feature.
