PHP Fatal error: Nesting level too deep - recursive dependency? when logging an 
object with recursive dependancies
------------------------------------------------------------------------------------------------------------------

                 Key: LOG4PHP-127
                 URL: https://issues.apache.org/jira/browse/LOG4PHP-127
             Project: Log4php
          Issue Type: Bug
          Components: Code
    Affects Versions: 2.0
         Environment: linux ubuntu 8.04
php 5.2
Log4php 2.0.0
            Reporter: David Pattison


I ran into a problem when you try to log an object with a circular dependency, 
such as $GLOBALS
here is a phpsh example:

php> require 'Logger.php';

php> Logger::getLogger('foo')->debug($GLOBALS);
array (
  'GLOBALS' => 
  array (
    'GLOBALS' => 
    array (
      'GLOBALS' => 
      array (

Fatal error: Nesting level too deep - recursive dependency? in 
/Users/davidp/Documents/workspace/zoosk-trunk-features/tools/include/vendor/log4php/renderers/LoggerRendererDefault.php
 on line 49

I am planing to patch my system so it uses print_r() which will not die in 
theses cases.

When I do that I would get this output:
php> require 'Logger.php';Logger::getLogger('foo')->debug($GLOBALS);
Thu Oct 14 18:58:48 2010,051 [2688] DEBUG foo - Array
(
    [GLOBALS] => Array
 *RECURSION*
    [_ENV] => Array
        (
            [TERM_PROGRAM] => Apple_Terminal
            [SHELL] => /bin/bash
            [TERM] => xterm-color
            [TMPDIR] => /var/folders/ME/ME4jssgwHQKMN3vofuUXEU++03M/-Tmp-/
            [Apple_PubSub_Socket_Render] => /tmp/launch-pRh4q5/Render
            [TERM_PROGRAM_VERSION] => 273
... ommited...

some links about theses two methods:
