[Bug 1198882] Re: __toString() which stores $this reference triggers segfault

[Alexey Skryabin]

** Description changed:

- DISTRIB_DESCRIPTION="Ubuntu 12.04.2 LTS"
- php --version
- PHP 5.3.10-1ubuntu3.6 with Suhosin-Patch 
+ Description:
+ Passing object with __toString() causes segfault in random script iteration. When casted to string beforehand, it runs OK.
  
+ Test case:
  Code as
  <?php
  
  class A {
          public $a;
          public function __toString()
          {
                  $this->a = $this;
                  return 'waa?';
          }
  }
  
  $a = new A;
  echo trim($a);
  echo trim($a->a);
  
  ?>
  crashes in CLI, and run as php mod in apache
+ 
+ Enviroment:
+ DISTRIB_DESCRIPTION="Ubuntu 12.04.2 LTS"
+ php --version
+ PHP 5.3.10-1ubuntu3.6 with Suhosin-Patch
