The following program prints FAILED; it should print PASSED
as per RM 3.4(27), which states:
-- "For the execution of a call on an inherited subprogram,
-- a call on the corresponding primitive subprogram of the
-- parent or progenitor type is performed; the normal conversion
-- of each actual parameter to the subtype of the corresponding
-- formal parameter (see 6.4.1) performs any necessary type
-- conversion as well."
