19 * This test calls json_parse_int64 with a variety of different strings.
20 * It's purpose is to ensure that the results are consistent across all
21 * different environments that it might be executed in.
22 *
23 * This always exits with a 0 exit value. The output should be compared
24 * against previously saved expected output.
