Sorry, this bug is not entirely fixed.
Reproducing Script:
Similar to the previous one, but with an additional ob_end_clean()
<?php
function f()
{
$data = ob_get_contents();
while(@ob_end_clean());
ob_start('ob_gzhandler');
$step = strlen($data)/2;
echo substr($data, 0, $step);
ob_flush();
echo substr($data, $step);
}
register_shutdown_function('f');
while(@ob_end_clean());
ob_start();
echo '<pre>';
readfile(__FILE__);
?>

Description:
------------
ob_gzhandler does not always append a trailing NUL byte to the deflated
string, resulting in warnings in debug mode.
