on php 5.3.27.
The problem is quite difficult to reproduce, as it greately depends on the 
filename, length of arguments etc.
Therefore I run it in a loop with different length of an argument passed to the 
script.
Sometimes uncommenting the line with echo "Y\n"; (even though it is obviously 
unreachable) helps to cause the error.
Sometimes I have to use ~/test.php or ./test.php instead of test.php as a 
filename to trigger the Segfault.

Once I find a good combination of filename and arguments, the problem is 
persistent and can be reproduced 100% of times for that combination.

Test script:
---------------
cat test.php
<?php
class A{
  function __construct(){
    register_shutdown_function(array(__CLASS__, 'handle_shutdown'));

    echo "X\n";
    while(1){
      $t[]=new B();
    }
 //   echo "Y\n";
  }
  static public function handle_shutdown(){
    echo "B\n";
    $b=new B();
    $b=null;
  }
}
class B{
}
$a=new A();
?>

for((n=0;n<100;++n));
do 
  echo $n;
  php-5.3.27/bin/php ~/test.php `for((i=0;i<n;++i));do echo -n a;done`;
done



Expected result:

72 bytes) in /home/jlopuszanski/test.php on line 8
