Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

There's no gz_handler, ie. you didn't actually start any output buffer.

ob_gzhandler is only available if PHP was compiled with --with-zlib
 [2006-03-30 19:53 UTC] caio53 at gmail dot com 
phpinfo();
ZLib Support 	enabled
Stream Wrapper support 	compress.zlib://
Stream Filter support 	zlib.inflate, zlib.deflate
Compiled Version 	1.2.3
Linked Version 	1.2.3

and function_exists('ob_gzhandler') returns true

Please try using this CVS snapshot:

  http://snaps.php.net/php5.1-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5.1-win32-latest.zip

Works fine here.
