This is due to bad use of term_ref/2 (see the doc). If a Ref is
specified (e.g. 12) you should be sure that it corresponds to a term
(i.e. it is a valid Ref). It is not the case here. The only way to be
ensure this is to reuse a Ref given by term_ref.

Yes, it is how ensure_linked/1 works. It simply ensures the specified
predicate is linked and does not specify anything else about other
predicates.
