[Rd] Invalidating inaccessible SEXP?

Is there a (C or R) function to invalidate the relevant parts of SEXP
/ data that are inaccessible? My problem is in tracking down
protection and other memory mismanagement bugs, where I have to rely
on luck to invalidate or overwrite data to trigger a detectable
error. This makes it hard to track down a bug (it sometimes doesn't
occur), or to know that a patch fixes the problem.
