-- CHECK THAT LENGTHS MUST MATCH IN ARRAY AND SLICE ASSIGNMENTS.
-- MORE SPECIFICALLY, TEST THAT ATTEMPTED ASSIGNMENTS BETWEEN
-- ARRAYS WITH NON-MATCHING LENGTHS LEAVE THE DESTINATION ARRAY
-- INTACT AND CAUSE CONSTRAINT_ERROR TO BE RAISED.
-- (OVERLAPS BETWEEN THE OPERANDS OF THE ASSIGNMENT STATEMENT
-- ARE TREATED ELSEWHERE.)
-- THIS IS A SPECIAL CASE IN
-- DIVISION D : NULL ARRAYS WHOSE LENGTHS ARE NOT DETERMINABLE
-- STATICALLY
-- WHICH (THE SPECIAL CASE) TREATS TWO-DIMENSIONAL ARRAYS WHOSE LENGTH
-- ALONG ONE DIMENSION IS GREATER THAN INTEGER'LAST AND WHOSE
-- LENGTH ALONG THE OTHER DIMENSION IS 0 .
-- AN ADDITIONAL OBJECTIVE OF THIS TEST IS TO CHECK WHETHER LENGTH
-- COMPARISONS (AND LENGTH COMPUTATIONS) CAUSE CONSTRAINT_ERROR
-- TO BE RAISED.
