Description:
------------
It looks as if when PHP is doing preg_replace and there are a lot of ()
values, then it just dies
With my example code, it'll die when doing preg_replace
I've tried a few values of $regexp on line 2
/<(.|\n)*>/ - it dies
/<(.)*>/ - it dies
/<.*>/ - it works fine
If the $test string is 1844 characters long it works fine, if it's 1845
characters long it dies.
It doesn't matter whether the string actually matches or not, it's the
number of characters it's trying to match.
The problem doesn't seem to happen with preg_match
Reproduce code:
---------------
<?php
$regexp = "/<(.|\n)*>/";
$stringlength = 1845;
echo "test start \n";
$test = '<' . str_repeat('x', $stringlength - 1);
$test = preg_replace($regexp,"",$test);
echo "test done\n";
?>
Expected result:
----------------
test start
test done
Actual result:
--------------
<nothing>
