User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20040914 (not Googlebot) Build Identifier: CVS js Followup to bug 304376: The arguments object is still affected by assignment to Object. ECMA 262-3 says (10.1.8): The value of the internal [[Prototype]] property of the arguments object is the original Object prototype object, the one that is the initial value of Object.prototype (section 15.2.3.1). Reproducible: Always Steps to Reproduce: js> 0, function () { return arguments.join() }( 1, 2, 3 ); typein:1: TypeError: arguments.join is not a function js> Object= Array, function () { return arguments.join() }( 1, 2, 3 ); 1,2,3 Expected Results: Should still throw TypeError.

Error objects are affected, too: js> try{x.y}catch(e){e.valueOf()} ReferenceError: x is not defined js> Error= Number function Number() { [native code] } js> try{x.y}catch(e){e.valueOf()} typein:3: TypeError: Number.prototype.valueOf called on incompatible Error Don't know if this should be a different bug.

Taking, I'll fix Error and any others in the same patch. /be

Fixed. /be

Fails how, what does the printStatus show as the result of arguments.join()? Since this works in the shell, I'd like to close the bug again. A followup bug would be better, since the core engine bug is in fact fixed. /be
