     38 * SUMMARY: Testing functions having duplicate formal parameter names
     39 *
     40 * SpiderMonkey was crashing on each case below if the parameters had
     41 * the same name. But duplicate parameter names are permitted by ECMA;
     42 * see ECMA-262 3rd Edition Final Section 10.1.3
     43 *
     44 * NOTE: Rhino does not have toSource() and uneval(); they are non-ECMA
     45 * extensions to the language. So we include a test for them at the beginning -
     46 */
