PHP Bug Type: *Regular Expressions
Bug description: preg_match returns false negative on > 100 kB strings for
some patterns
Description:
------------
preg_match fails for some patterns when the searched string exceeds around
100300 bytes. It matches for same strings if enough text is removed from
the middle part which gets captured by the pattern when working correctly.
Also the exact same regexp works fine for perl on unshortened output.
Reproduce code:
---------------
<?php
//foo.html >= 100 kB
$contents = file_get_contents("foo.html");
$matches = array();
preg_match('%<BODY\s*>.*?</H[1-6]>(.+?)</BODY>%si', $contents, $matches);
//$matches is empty
var_dump($matches);
?>
Expected result:
----------------
array(1) {
[0]=>
string(12935) "/*lots of html*/
}
Actual result:
--------------
array(0) {
}
