Summary: set-difference ... :test 'equalp

Initial Comment:
Evaluation of

(set-difference
  '(0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0)
  '(0 0 0 0 0 0)
  :test 'equalp)

gives

*** - MAKE-HASH-TABLE: illegal :TEST argument
SYSTEM::FASTHASH-EQUALP
The following restarts are available:
USE-VALUE      :R1      You may input a value to be
used instead.
ABORT          :R2      ABORT

In general, (set-difference x y :test 'equalp) gives
the message above when x has 16 elements or more and y
has 6 elements or more. I have seen no problems with
:test 'equal or when x or y have fewer elements than
the limits of 16 and 6, respectively.

Cheers,
Klaus <gr...@di...>
