Description:
------------
positive lookbehind is causing seg fault in preg_match_all, If i take
out the positive lookbehind, it doesn't crash.
Reproduce code:
---------------
<?php
echo "starting\n";
$subject = "enum('active','inactive','rockin\'')";
$pattern = "/'(([^']*((?<=\\\\)')?)*)'/";
preg_match_all($pattern,$subject ,$matches);
print_r($matches);
echo "done.";
Expected result:
----------------
starting
Array
(
[0] => Array
(
[0] => 'active'
[1] => 'inactive'
[2] => 'rockin\''
)
[1] => Array
(
[0] => active
[1] => inactive
[2] => rockin\'
)
[2] => Array
(
[0] =>
[1] =>
[2] =>
)
[3] => Array
(
[0] =>
[1] =>
[2] => '
)

done.
