Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Your object looks like this:
object(a)#1 (1) {
  ["b"]=>
  object(b)#2 (1) {
    ["a"]=>
    &object(a)#1 (1) {
      ["b"]=>
      object(b)#2 (1) {
        ["a"]=>
        *RECURSION*
      }
    }
  }
}
Which should explain the error message you are seeing.

Description:
------------
The code (attached) produces the following error: Fatal error: Nesting
level too deep - recursive dependency? in /home/tim/www/crash2.php on
line 15

I started getting this bug with some code we are running and did some
google searches and found something on the php-dev list (where the
sample code is from) from 9/22/02:
http://www.geocrawler.com/archives/3/5/2002/9/50/9731982/

This happens on our Linux and FreeBSD boxes running PHP 4.3.2, 4.3.1,
and I just installed the latest CVS version (php4-STABLE-200307212330)
and got the same error.  For the CVS version I configured using
"./configure" and ran it through the command line on a Red Hat 8 box.

I saw other mentions of this error floating around but couldn't find
anything recent so sorry if this is a repeat.

Reproduce code:
---------------
<?php
    class A {
        var $b;
         function A() { $this->b =& new B($this); }
    }    
     
    class B {
        var $a;
        function B(&$a) { $this->a =& $a; }
    }    
     
    $one =& new A;
    $two =& $one; 
    
    if ($one == $two) {  // <-- fatal error here
        echo "Same object\n";
    } else {
        echo "not the same object\n";
    }
?> 

Expected result:
----------------
Expected it to not give a fatal error.
