New issue 3172 by [email protected]: About "issue 3064, Tighten up
Object.prototype.__proto__ "
http://code.google.com/p/v8/issues/detail?id=3172
In this commit https://code.google.com/p/v8/source/detail?r=19479 , I think
code below
if (IS_SPEC_OBJECT(proto) || IS_NULL(proto) && IS_SPEC_OBJECT(this)) {
%SetPrototype(this, proto);
}
should be
if ((IS_SPEC_OBJECT(proto) || IS_NULL(proto)) && IS_SPEC_OBJECT(this)) {
%SetPrototype(this, proto);
}
Test case:
V8 version 3.25.0 [console: dumb]
d8> a=1
1
d8> b={}
{}
d8>
Object.getOwnPropertyDescriptor(Object.prototype, "__proto__").set.call(a,b)
Expected: silently does nothing
Actual: (d8):1: illegal access
