michael@0:  * SUMMARY: Testing cloned function objects
michael@0:  * See http://bugzilla.mozilla.org/show_bug.cgi?id=127557
michael@0:  *
michael@0:  * Before this bug was fixed, this testcase would error when run:
michael@0:  *
michael@0:  *             ReferenceError: h_peer is not defined
michael@0:  *
michael@0:  * The line |g.prototype = new Object| below is essential: this is
michael@0:  * what was confusing the engine in its attempt to look up h_peer
