When I run following code, Apache is crashed by an inifinite loop.
Code:
<?php
class A {
   var $class_b;
   
   function A () {
      $this->class_b = new B($this);
   }
}

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

require 'Smarty.class.php';
$a = new A();
$smarty = new Smarty;
$smarty->debugging = true;
$smarty->assign("Infinite loop", $a);
$smarty->display('index.tpl');
?>


When I turn debugging off, index.tpl is displayed correctly.
smarty_modifier_debug_print_var function calls recursively themself.

Correct. Don't expect this to be fixed.

why not? wouldn't a simple maximum recursion depth solve the problem?

a

Code:
if($depth > 10) return $var;


(or a bit more beautified) should do the job, no?

Hmm, this causes the same problem:

index.php

Code:
include 'index.php';


Maybe the PHP guys should fix that?
