Title:
Undefined behaviour in defstruct use

Public bug reported:
A first step in using clasp as a compilation host for sbcl
** Affects: sbcl (Ubuntu)
Importance: Undecided
Status: New

Public bug reported:
sbcl seem to rely on undefined behaviour in its use of defstructs with
constuctors that don't initialize all slots (sbcl seem to assume that
these slots are initialized to nil).
Example:
(defstruct (hugo (:constructor make-hugo (a))) a b)
(hugo-b (make-hugo 23))
returns nil
