Bug 79843 – Should not box `this` in strict-mode getters

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: JavaScriptCore

[Domenic Denicola]

The following code should log "number" according to the ES5 spec, section 10.4.3 [1]:


Object.defineProperty(Object.prototype, "getMe", {
    get: function () {
        "use strict";
        console.log(typeof this);
    }
});

(0).getMe;


Instead it logs "object".

Please retest in a nightly, this is already fixed. :-)
