Subject: I caught the aggregation bug!

Hi,

This short script can reproduce the aggregation bug I reported above.

class bar {
 
   function doit()
   {
      print " Doing...\n";
   }
}

class foo {

   function foo()
   {
       print_r(aggregation_info($this));
       aggregate($this, "bar");
   }
   
   function spawn()
   {
       return new foo();
   }
}

$a = new foo();
$a->doit();
$b = $a->spawn();
$b->doit();
unset($a);
$c = $b->spawn();
$c->doit();

Besides 'unset($a)', '$a = new foo()' will also cause the same problem.
