Description:
------------
One of my regular expressions leads to return of emptiness to functions preg_replace if the initial line contains more than 991 blanks. Example more low. The first line works, the second dies also I lose all contents.

Test script:
---------------
$text = 'test'.str_repeat(' ', 991).'test'; // work
$text = 'test'.str_repeat(' ', 992).'test'; // empty :(

if ($text = preg_replace('/(.*?\s+)"([^\s]+.*?)/', '$1<quot1>$2', $text)) {
    echo "GOOD\n";
} else {
    echo "BAD\n";
}
