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