Summary

0001385: Can not fetch IS_INDIRECT private properties

Description

`property_get -n $b->*A*a->children` will always result in "can not get property" error message.

(affected all versions of PHP >=7)

Steps To Reproduce

e.php
<?php

class A {
  private $a;
  public function __construct($a) {
    $this->a = $a;
  }
}
class B extends A {
  public $a;
  public function __construct($privA, $a) {
    parent::__construct($privA);
    $this->a = $a;
}

$chain = new A(new B(new A(1), 2));
echo 1; // breakpoint here

---- end of file ----

Now if we try to run this script until the breakpoint and call `property_get -d 0 -c 0 -n $chain->a->*A*a->a` we will get an error instead of `1`.
