Bug description:  Pcre functions doesn't work well

Description:
------------
PCRE Library Version => 7.0 18-Dec-2006
this version PCRE seems doesn't work well with PHP.
I met same problem with php5.2.1+PCRE 7.0 in FreeBSD, resolved by
downgrading to PCRE 6.7(blog detail:
http://translate.google.com/translate?u=http%3A%2F%2Fhi.baidu.com%2Frainchen%2Fblog%2Fitem%2Fb6321038cf289bf3b211c7bf.html&langpair=zh%7Cen&hl=en&newwindow=1&ie=UTF-8&oe=UTF-8&prev=%2Flanguage_tools)

I had tried to set php.ini as :
[Pcre]
pcre.backtrack_limit=100000
pcre.recursion_limit=100000

but not helping

Reproduce code:
---------------
<?php
$str = "repeater id='loopt' dataSrc=subject colums=2";
preg_match_all("/(['\"])((.*(\\\\\\1)*)*)\\1/sU",$str,$str_instead);

echo "<xmp>";
print_r($str_instead);
?>

Expected result:
----------------
<xmp>Array
(
    [0] => Array
        (
            [0] => 'loopt'
        )

    [1] => Array
        (
            [0] => '
        )

    [2] => Array
        (
            [0] => loopt
        )

    [3] => Array
        (
            [0] => loopt
        )

    [4] => Array
        (
            [0] =>
        )

)

Actual result:
--------------
<xmp>Array
(
    [0] => Array
        (
        )

    [1] => Array
        (
        )

    [2] => Array
        (
        )

    [3] => Array
        (
        )

    [4] => Array
        (
        )

)
