Yeah, you're not the first to complain about this.  To my mind that
coding is not pretty, not cute, and not portable: there's not even
a good reason to believe that dereferencing the pointer would result
in a crash.  Perhaps the author can explain to us why this is better
than just assigning NULL.

Actually, looking around a bit there, it's not even clear why
we should be booby-trapping the value of an unchanged column in
the first place.  So I'd say that not only is the code dubious
but the comment is inadequate too.
