--
-- OBJECTIVE:
--    Check that components of Stream_Element_Array are aliased.  (Defect
--    Report 8652/0044).
--
-- APPLICABILITY CRITERIA:
--    All implementations must attempt to compile this test.
--
--    For implementations for which Stream_Element'Size is a multiple of
--    System.Storage_Unit, this test must execute.
--
--    For other implementations, if this test compiles without error messages
--    at compilation, it must bind and execute.
--
-- PASS/FAIL CRITERIA:
--    For implementations for which Stream_Element'Size is a multiple of
--      System.Storage_Unit, this test must execute, report PASSED, and
--      complete normally, otherwise the test FAILS.
--
--    For other implementations:
--      PASSING behavior is:
--        this test executes, reports PASSED, and completes normally
--      or
--        this test produces at least one error message at compilation, and
--        the error message is associated with one of the items marked:
--           -- N/A => ERROR.
--
--      All other behaviors are FAILING.
--
--
-- CHANGE HISTORY:
--    12 FEB 2001   PHL   Initial version
--    15 MAR 2001   RLB   Readied for release.
