Answer 1

Try disabling pcre.jit (don't use PCRE's just-in-time compilation):

<?php
ini_set("pcre.jit", "0");

$str = "<div>";
for ($x=1;$x<=327;$x++){
    $str .= "1234567890";
}
$str .="123456";
$str .= "</div>";

$w1 = "/<div>((.*?|\n)*)<\/div>/";
preg_match_all($w1, $str, $matches);
print_r($matches);
?>

You should execute preg_last_error() to know what has failed.
