michael@0:  * SUMMARY: Testing functions having duplicate formal parameter names
michael@0:  *
michael@0:  * SpiderMonkey was crashing on each case below if the parameters had
michael@0:  * the same name. But duplicate parameter names are permitted by ECMA;
michael@0:  * see ECMA-262 3rd Edition Final Section 10.1.3
michael@0:  *
michael@0:  * NOTE: Rhino does not have toSource() and uneval(); they are non-ECMA
michael@0:  * extensions to the language. So we include a test for them at the beginning -
