      1 /* A switch on a char-typed selector. The selector is narrowed to 8 bits, so
      2  * the dispatch compares byte values; this exercises the sub-register compare
      3  * path feeding the switch. volatile char defeats folding. The character 'B'
      4  * (0x42) selects the case returning 42. Exit code 42. */
