Description:
------------
strange bug, this code skip all characters expect the end \n (\r is
find).

This is the same when .*? is in subpattern.

Reproduce code:
---------------
$str = "test\ntest\r\n";

function v($s) {
echo '"'.$s.'"'."\n---\n";
}

echo v(preg_replace('#^.*$#s','', $str));
echo v(preg_replace('#^.*?$#s','', $str));
echo v(preg_replace('#^.*$#Us','', $str));

Expected result:
----------------
""

Actual result:
--------------
