Bug Description

Found over the weekend with the random tester. This bug still occurs in current snapshot.

(compile nil
         '(lambda (a b)
           (declare (notinline min ash conjugate oddp >=))
           (declare (optimize (debug 3) (compilation-speed 0) (safety 1) (space 3) (speed 0)))
           (if (and (or t (>= a)) (oddp 0))
               (prog2 0
                   0
                 (labels ((%f18 (f18-1 f18-2 f18-3 &key)
                            6965670824543402))
                   (%f18 a 0 b))
                 )
               (conjugate
                (dotimes (iv4 0 0)
                  (catch 'ct7
                    (ash
                     (the integer
                       (ignore-errors
                         (ignore-errors (throw 'ct7 -20372435344354))))
                     (min 12 a))))))))

The value
  #<SB-KERNEL:NAMED-TYPE NIL>
is not of type
  SB-KERNEL:VALUES-TYPE
   [Condition of type TYPE-ERROR]

Restarts:
 0: [ABORT] Exit debugger, returning to top level.
