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