  22 * SUMMARY: Regression test for Bugzilla bug 99663
  23 * See http://bugzilla.mozilla.org/show_bug.cgi?id=99663
  24 *
  25 *******************************************************************************
  26 *******************************************************************************
  27 * ESSENTIAL!: this test should contain, or be loaded after, a call to
  28 *
  29 *                         version(120);
  30 *
  31 * Only JS version 1.2 or less has the behavior we're expecting here -
  32 *
  33 * Brendan: "The JS_SetVersion stickiness is necessary for tests such as
  34 * this one to work properly. I think the existing js/tests have been lucky
  35 * in dodging the buggy way that JS_SetVersion's effect can be undone by
  36 * function return."
  37 *
  38 * Note: it is the function statements for f1(), etc. that MUST be compiled
  39 * in JS version 1.2 or less for the test to pass -
  40 *
  41 *******************************************************************************
  42 *******************************************************************************
  43 *
  44 *
  45 * NOTE: the test uses the |it| object of SpiderMonkey; don't run it in Rhino -
