Description Paul Irish 2011-08-08 15:56:28 PDT 
[].indexOf.call(undefined, 6);

^ should throw a TypeError according to spec....

from: http://es5.github.com/#x15.4.4.14

1. Let O be the result of calling ToObject passing the `this` value as the argument.

and from the ToObject definition http://es5.github.com/#x9.9 ...

if ArgumentType is Undefined, then Throw a TypeError exception

Current behavior: JSC returns -1. V8 throws TypeError.
