Description:
------------
Hello, this code crashes Apache with PHP on Windows. I know that this regex is not quite correct, but still.

The solution is to increase Apache stack, but I think there should be some check in PHP to prevent crashing.

Test script:
---------------
$text = '
test_test_test_test_test_test_test_test_test_test_test_test_test_test_test
test_test_test_test_test_test_test_test_test_test_test_test_test_test_test
test_test_test_test_test_test_test_test_test_test_test_test_test_test_test
test_test_test_test_test_test_test_test_test_test_test_test_test_test_test
test_test_test_test_test_test_test_test_test_test_test_test_test_test_test
test_test_test_test_test_test_test_test_test_test_test_test_test_test_test
test_test_test_test_test_test_test_test_test_test_test_test_test_test_test
test_test_test_test_test_test_test_test_test_test_test_test_test_test_test
test_test_test_test_test_test_test_test_test_test_test_test_test_test_test
';

$text = preg_replace('/([\n]|.)*/','test',$text);

echo $text;
