Description:
------------
with php 5.3.13, 5.3.14 and 5.4.3 the script is working well while it delivers the following error with php 5.4.4:

ob_start(): output handler 'ob_gzhandler' conflicts with 'zlib output compression'

webserver is nginx 1.2 without deflate mods using php via fcgi

php.ini setting 'zlib.output_compression' is turned off

Test script:
---------------
error_reporting(E_ALL);

$zlib_oc = ini_get('zlib.output_compression');

if(empty($zlib_oc)) {

    ob_start('ob_gzhandler');
}

echo 'test';

Expected result:
----------------
test

Actual result:
--------------
test with the error message attached that was mentioned above

there is also a second error message, but that might be clear:

ob_start(): failed to create buffer

update: the issue always starts on first refresh, so it might be caused by the fix for bug 60761, just guessing.

Same error for me with this code:

	ob_start('ob_gzhandler');

Windows 7, Apache 2.4, PHP 5.4.4 thread-safe, "zlib.output_compression" is set to "off" in php.ini.

The bug disappears if I add "php_flag zlib.output_compression off" in .htaccess file of specific host. So, probably, the bug is that global (from php.ini) "zlib.output_compression=off" setting is just _ignored_ in PHP 5.4.4.

bug 55544 is about this issue, too. between stable php 5.4.0 and 5.4.3 it was fixed and seems to fail again now.

Seems to be a problem in merging the fix to actual branch, which releases are made of.
This commit:
http://git.php.net/?p=php-src.git;a=commit;h=85a62e9086db7a8ddfcda4ab1279a2439935f8d5
really fixes the problem, but relevant line is not present in php-5.4.3 and php-5.4.4.

The Error is still there in Debians php 5.4.5-dev.

Hi,
the Bug was fixed by Mike in this commit:
http://git.php.net/?p=php-
src.git;a=commit;h=85a62e9086db7a8ddfcda4ab1279a2439935f8d5

On the 15th of May, the following commit by mike removed the added line by the 
above commit:
http://git.php.net/?p=php-
src.git;a=commitdiff;h=0ad53bfd7da12a92a46c08e3fff579a15026b88b

I'not shure, if this was realy intended... So maybe mike can take over this 
ticket... Would be great, to have a working ob_gzhandler again in 5.4

Same problem here with version 5.4.4 and 5.4.5RC1 from php.net. OS is Centos 6.2, webserver is Apache using PHP via php-fpm.

The configuration that I use in php-fmp.conf is:
php_flag[output_buffering] = on
php_flag[zlib.output_compression] = off
php_value[output_handler] = ob_gzhandler

checked this bug against the new php versions:

5.3.15 runs well, but 5.4.5 still has this issue.
