-- OBJECTIVE:
--    CHECK THAT WHEN A VARIABLE OR CONSTANT HAVING A CONSTRAINED
--    ACCESS TYPE IS DECLARED WITH AN INITIAL NON-NULL ACCESS VALUE,
--    CONSTRAINT_ERROR IS RAISED IF AN INDEX BOUND OR A DISCRIMINANT
--    VALUE OF THE DESIGNATED OBJECT DOES NOT EQUAL THE CORRESPONDING
--    VALUE SPECIFIED FOR THE ACCESS SUBTYPE.

-- HISTORY:
--    RJW 07/20/86  CREATED ORIGINAL TEST.
--    JET 08/05/87  ADDED DEFEAT OF DEAD VARIABLE OPTIMIZATION.
--    PWN 11/30/94  REMOVED TEST ILLEGAL IN ADA 9X.
