Way too specific.  Pointing to C data structures from IV slots is a
common pattern, sure, but even in the relatively unusual case where the
data structures are statically allocated there's no reason to expect
that the pointer would correspond to an external-linkage symbol in the
module's .so.  That they do in the case of Encode is an accident of
implementation, not an architectural necessity.
