I changed the code to:
........
Persistent<Object> self = Persistent<Object>::New(args.Holder());
self.MakeWeak(p, Point_Destroy);
self->SetInternalField(0, External::New(p));
return self;
}
void Point_Destroy(Persistent<Object> self, void* parameter)
{
delete static_cast<Point*>(parameter);
}
because in the previous version were some problems when I tested it
with the javascript file.
