For cases where larger literals would hit parser limits,
or be in conflict with style guides, maybe some compiler
arithmetic prevents it, thus

   Offset_512_Too : constant :=
     96593031294966694980094354007163104660904187456726 * 10**(2*50 +4) +
     37896108374329434462657994582932197716438449813051 * 10**(1*50 +4) +
     892206539805784495328239340083876191928701583869517785;

private

   Check : constant := Boolean'Pos  -- compile time check
     (case True is
        when  Offset_512 = Offset_512_Too => True,
        when  False => False);


The private part given as an example of assertions just when
they should be made compile time assertions.
