  25 -- OBJECTIVE:
  26 --     CHECK THAT CONSTRAINT_ERROR IS RAISED WHEN THE SUBTYPE
  27 --     INDICATION IN A CONSTANT OBJECT DECLARATION SPECIFIES A
  28 --     CONSTRAINED SUBTYPE WITH DISCRIMINANTS AND THE INITIALIZATION
  29 --     VALUE DOES NOT BELONG TO THE SUBTYPE (I. E., THE DISCRIMINANT
  30 --     VALUE DOES NOT MATCH THOSE SPECIFIED BY THE CONSTRAINT).
  31
  32 -- HISTORY:
  33 --     RJW 08/25/86  CREATED ORIGINAL TEST
  34 --     VCL 08/19/87  CHANGED THE RETURN TYPE OF FUNTION 'INIT' IN
  35 --                   PACKAGE 'PRIV2' SO THAT 'INIT' IS UNCONSTRAINED,
  36 --                   THUS NOT RAISING A CONSTRAINT ERROR ON RETURN FROM
  37 --                   'INIT'.
