Please try using this CVS snapshot:

  http://snaps.php.net/php5-STABLE-latest.tar.gz
 
For Windows:

I believe this was a dom problem whiich was already fixed in CVS

I forgot to mention that in PHP 5.0.2 everything works correctly...

Description:
------------
When references between more objects, and on of objects is extended
from domDocument, has reference to it caller object and use its
property in vsprinf, reference to orignal object is destroyed or
wrongly managed by garbageCollector... Really confusing -> could be
workarounded by calling method of domDocument extended object from
outside of referenced object...


Reproduce code:
---------------
<?php
class a {
  public $a = array(1,2,3);
  function aa($b){ $b->bb(); }
}
class b extends domDocument {
  public $a = NULL;
  function bb(){ $x = vsprintf('www %s www %s www %s www', $this->a->a)
; }
}
class x {
  public $a = null; public $b = null;
  function __construct() {
    $this->a = new a(); $this->b = new b();
    $this->b->a = $this->a;
    var_dump('Object a',$this->a, 'Object b',$this->b);
    $this->a->aa($this->b);
    var_dump('Object a',$this->a, 'Object b',$this->b);
  }
}
$x = new x();
?>

Expected result:
----------------
string(8) "Object a"
object(a)#2 (1) {
  ["a"]=>
  array(3) {
    [0]=>
    int(1)
    [1]=>
    int(2)
    [2]=>
    int(3)
  }
}
string(8) "Object b"
object(b)#3 (1) {
  ["a"]=>
  object(a)#2 (1) {
    ["a"]=>
    array(3) {
      [0]=>
      int(1)
      [1]=>
      int(2)
      [2]=>
      int(3)
    }
  }
}
string(8) "Object a"    <<< RIGHT
object(a)#2 (1) {
  ["a"]=>
  array(3) {
    [0]=>
    int(1)
    [1]=>
    int(2)
    [2]=>
    int(3)
  }
}
string(8) "Object b"
object(b)#3 (1) {
  ["a"]=>
  object(a)#2 (1) {
    ["a"]=>
    array(3) {
      [0]=>
      int(1)
      [1]=>
      int(2)
      [2]=>
      int(3)
    }
  }
}


Actual result:
--------------
string(8) "Object a"
object(a)#2 (1) {
  ["a"]=>
  array(3) {
    [0]=>
    int(1)
    [1]=>
    int(2)
    [2]=>
    int(3)
  }
}
string(8) "Object b"
object(b)#3 (1) {
  ["a"]=>
  object(a)#2 (1) {
    ["a"]=>
    array(3) {
      [0]=>
      int(1)
      [1]=>
      int(2)
      [2]=>
      int(3)
    }
  }
}
string(8) "Object a"
string(8) "Object a"  <<<  WRONG
string(8) "Object b"
object(b)#3 (1) {
  ["a"]=>
  string(8) "Object a"
}
