Description:
------------
The server crashes if I want to filter a string which has more
characters than 
2264.

The string in my test-code below contains 2265 characters.

If I call this script using the apache-php-mod I get an empty response.
Otherwise if I call this script by using the command-line it crashes
either - but 
now I get the error-message: Segmentation fault

I have tested some other filters and it's only FILTER_VALIDATE_EMAIL who
crashes 
in my tests.

You can check the length of the string first by using this information:
http://email.about.com/od/emailbehindthescenes/f/address_length.htm

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

$extremeString =
'01234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678
