I have a problem when using two-way references.
The simplest case I could dig out:


<pre>

class B
{
  var $a;
  function B(& $a)
  {
    $this->a = & $a;
  }
}

class A
{
  var $b;
  function A()
  {
    $this->b = & new B($this);
  }
}

$a = new A();

$a->x = "ax";

print $a->b->a->x;

<pre>

I think this should print out "ax". However it doesn't.

If I add the following line after constructing $a:

$a->b->a = &$a;

then it works, it prints out "ax".

Or, if I define A like this:

<pre>

class A
{
  var $b;
  function A()
  {
    $this->b = & new B($this);
  }
  function setBsA()
  {
    $this->b->a = & $this;
  }
}

</pre>

and call setBsA() after contructing, it still works.
