Description:
------------
Long entities can cause a buffer overflow because the loop only guarantees 40 
bytes available in beginning.

Test script:
---------------
<?php
echo 
htmlspecialchars('"""""""""""""""""""""""""""""""""""""""""""""&#x000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000005;',
ENT_QUOTES, 'UTF-8', false), "\n";
