Dear internals,
I stumbled upon the following odd error message from PHP which I was not expecting.
Here is a small example that triggered the error with 5.2.2, 5.2.3 and a php5.2-200706052030 snapshot.
<?php
class class1{
public $c2;
function __construct($c2){
$this->c2 = $c2;
}
}
class class2{
public $c1;
function setC1($c1){
$this->c1 = $c1;
}
function test(){
echo $this == $this->c1->c2?'equals':'not equals'; // Somehow this if statement triggers the error.
}
}
$tt = new class2();
$t = new class1($tt);
$tt->setC1($t);
var_dump($t);
$tt->test();
?>
I get the error:
Fatal error: Nesting level too deep - recursive dependency? in /home/cyanox/DEV/test_object_recursion.php on line 15
Although it is obvious that there is a recursion I think this simple example should work without error.
Greetings,
Mark Sanders.
