25 -- OBJECTIVE
26 -- Check that if the index subtype of a string type is a modular subtype
27 -- whose lower bound is zero, then the evaluation of a null string_literal
28 -- raises Constraint_Error. This was confirmed by AI95-00138.
29 --
30 -- TEST DESCRIPTION
31 -- In this test, we have a generic formal modular type, and we have
32 -- several null string literals of that type. Because the type is
33 -- generic formal, the string literals are not static, and therefore
34 -- the Constraint_Error should be detected at run time.
