 Priority:  normal        |   Milestone:  Awaiting Review
Component:  General       |     Version:  3.0            
 Severity:  normal        |    Keywords:  gzdeflate      
--------------------------+-------------------------------------------------
 With my configuration below when I try to edit any post via "''/wp-
 admin/post.php?post=xxx&action=edit''" the page not responding in v3 and
 v301. I inspect the http traffic with wireshark then detect a bug (i think
 that its a PHP bug) in '''gzdeflate''' function.

 Source of problem is gzdeflate function in '''load-scripts.php''' at
 '''line 134'''. I think that it outputs bad data to browser causing the
 browser waits forever...

 '''At line 134''', If I select a different compression level diffent from
 3 then problem solves.

 Also, load-scripts.php script reads four js file into variable named $out
 then compress it and output to browser. Scripts are below:

 ./public_html/wp-includes/js/jquery/jquery.js[[BR]]
 ./public_html/wp-admin/js/utils.js[[BR]]
 ./public_html/wp-includes/js/quicktags.js[[BR]]
 ./public_html/wp-admin/js/editor.js[[BR]]

 If I change the content of any one of the js files above then problem
 fixed.

 '''My configurations are''':[[BR]]
 -WordPress 3.01[[BR]]
 -PHP 5.1.6 (cli) (built: Mar 31 2010 02:44:37)[[BR]]
 -Apache Server version: Apache/2.2.3 Server built: Apr 4 2010
