Description:
------------
Problem exists when I use file_get_contents or fopen

It causes httpd seg fault randomly



Test script:
---------------
<?php



$a =
file_get_contents('http://myproxy.com/get.php?url=http://www.google.pl');



?>



another:



<?php



if(@fopen('http://www.vorbis.com/files/1.0.1/windows/vorbis-tools-1.0.1-win32.zip','r'))
{

 echo 'File exists';

}



?>

Actual result:
--------------
