It sounds to me like your stack is too small, are you using it within Apache?

Can you try in CLI using php.exe t.php and then using php.exe -n t.php please?

t.php:

<?php
$mail = filter_var('the-total-length@of-an-entire-address.cannot-be-longer-than-two-hundred-and-fifty-four-characters.and-this-address-is-254-characters-exactly.so-it-should-be-valid.and-im-going-to-add-some-more-words-here.to-increase-the-lenght-blah-blah-blah-blah-bla.org', FILTER_VALIDATE_EMAIL);
file_put_contents('test.txt', $mail);
?>

Success!
test.txt has been created and contains the given string.

works with both:
php t.php
php -n t.php

Thnx for this, whenever I 'think' I have found a bug, I will try this first.
I'm gonna google "Apache stack too small" now.

Happy New Year!

See http://msdn.microsoft.com/en-us/library/xd3shwhf(v=vs.71).aspx

And no, no need to assign to me, there is no bug.

We do not control how apache is built nor how it is configured (stack size 
option).

Cheers.
