--

-- 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.
