Description:
------------
When using ob_start() followed by a ini_set('zlib.output_compression', true), 
using ob_flush() won't output anything, even if no zlib compression will happen.

This is a new bug since PHP 5.4.0, maybe linked to #61820

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

ob_start();

ini_set('zlib.output_compression', true);

echo "PHP VERSION ".phpversion()."\n";
ob_flush();
flush();

echo "You shouldn't have to wait to see me\n";
ob_flush();
flush();

sleep(5);


Expected result:
----------------
PHP VERSION 5.5.0-dev
You shouldn't have to wait to see me


Actual result:
--------------
PHP VERSION 5.5.0-dev
You shouldn't have to wait to see me
