  38 * SUMMARY: Testing cloned function objects
  39 * See http://bugzilla.mozilla.org/show_bug.cgi?id=127557
  40 *
  41 * Before this bug was fixed, this testcase would error when run:
  42 *
  43 *             ReferenceError: h_peer is not defined
  44 *
  45 * The line |g.prototype = new Object| below is essential: this is
  46 * what was confusing the engine in its attempt to look up h_peer
