Inspecting PCL objects in Franz.

[Stephen L Nicoud <snicoud@atc.boeing.COM>]

I can't inspect PCL objects in Franz Allegro CL.

I've searched the PCL mail archives and didn't see anything related 
to the inability to inspect PCL objects in Franz Allegro CL.

Allegro CL: 3.1.13
PCL: Victoria Day (the default PCL supplied with Allegro CL 3.1.13)
Sun 3/60

<cl> (defclass ship () (a b))

NIL 
<cl> (setq b (make-instance 'ship))

#<SHIP 124767061> 
<cl> (inspect b)
Error: Illegal vector object passed to svref: NIL
<cl> :zo
Evaluation stack:

 ->(ERROR "Illegal vector object passed to svref: ~s" NIL)
   (SVREF NIL 3)
   (INSPECT::INSPECT-CTL #<SHIP 124767061>)
   (INSPECT::INSPECT-PUSH #<SHIP 124767061> "(inspect ...)")
   (INSPECT #<SHIP 124767061>)
   (EVAL (INSPECT B))
