SpiderMonkey Internals
(otherwise, spidermonkey converts primitive values to objects before invoking their methods, per ecma 262-3 §11.2.1.) error handling spidermonkey has two interdependent error-handling systems: javascript exceptions (which are not implemented with, or even compatible with, any kind of native c/c++ exception handling) and error reporting.

JSClass.flags
standard constructors or prototypes (such as function.prototype.) objects that can end up with the wrong prototype object, if this flag is not present, include: arguments objects (ecma 262-3 §10.1.8 specifies "the original object prototype"), function objects (ecma 262-3 §13.2 specifies "the original function prototype"), and objects created by many standard constructors (ecma 262-3 §15.4.2.1 and others).

JS_LookupElement
the ecmascript standard also specifies this behavior: see ecma 262-3 §11.2.1, step 6.
