Description Justin Dolske [:Dolske] 2011-12-14 23:54:07 PST
20th section in

V519 The '* vp' variable is assigned values twice successively. Perhaps this is a mistake. Check lines: 711, 712.
jsdbgapi.cpp 712

JS_GetValidFrameCalleeObject(JSContext *cx, JSStackFrame *fp, jsval *vp)
    Value v;

    if (!Valueify(fp)->getValidCalleeObject(cx, &v))
        return false;
    *vp = v.isObject() ? v : JSVAL_VOID;
    *vp = v;
    return true;
