Bug description:  preg_match_all result not correct

Description:
------------
preg_match_all's result is correct before windows update !

But yesterday (2008-05-15) I update my windows xp by windows's Auto Update
, preg_match_all's result became not correct!


my OS: windows XP SP2 (Traditional Chinese)
php: 5.2.6 in windows

PCRE Library Version 	7.6 2008-01-28 

Reproduce code:
---------------
$array_matches = array();

$sql = 'SELECT b.* , u.account , u.name , u2.account as account2 , u2.name
as name2 FROM bbss as b LEFT JOIN users as u on (u.uid = b.post_uid) LEFT
JOIN users as u2 on (u2.uid = b.modified_uid) WHERE deleted = 0 AND
view_start_time <= NOW() ORDER BY bid DESC LIMIT 0 , 20';

$match_count = preg_match_all('/^(SELECT.*?)LIMIT/im', $sql,
$array_matches);


Expected result:
----------------
$match_count > 0;

$array_matches == 
Array(
  [0] => Array ( 'SELECT b.* , u.account , u.name , u2.account as account2
, u2.name as name2 FROM bbss as b LEFT JOIN users as u on (u.uid =
b.post_uid) LEFT JOIN users as u2 on (u2.uid = b.modified_uid) WHERE
deleted = 0 AND view_start_time <= NOW() ORDER BY bid DESC LIMIT 0 , 20' )

  [1] => Array ( 'SELECT b.* , u.account , u.name , u2.account as account2
, u2.name as name2 FROM bbss as b LEFT JOIN users as u on (u.uid =
b.post_uid) LEFT JOIN users as u2 on (u2.uid = b.modified_uid) WHERE
deleted = 0 AND view_start_time <= NOW() ORDER BY bid DESC ' )
)

Actual result:
--------------
$match_count == 0

$array_matches == Array ( [0] => Array ( ) [1] => Array ( ) )
