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:
