Comment (by kkmuffme):

 Multiple possible scenarios. I guess the easiest is to just turn on
 zlib.output_compression in the ini.

 Without server modification, I guess this should work too (would give a
 notice in current case, but notice is fixed with the PR):

 advanced-cache.php

 {{{#!php
 <?php
 function my_ob_cb( $output ) {
     return $output;
 }

 ob_start( 'my_ob_cb', 0, 0 );
 }}}
