Confirmed. The problem is that constant_value_1 has the following code:

      if (!init
          || !TREE_TYPE (init)
          || (integral_p
              ? !INTEGRAL_OR_ENUMERATION_TYPE_P (TREE_TYPE (init))
              : (!TREE_CONSTANT (init)
                 /* Do not return an aggregate constant (of which
                    string literals are a special case), as we do not
                    want to make inadvertent copies of such entities,
                    and we must be sure that their addresses are the
                    same everywhere.  */
=>               || TREE_CODE (init) == CONSTRUCTOR
                 || TREE_CODE (init) == STRING_CST)))


So it does not consider string constant as constant initializers. I think this
is probably breaking more than this warning.
