Bug description:preg_split with a subpattern fails on some specific input
Description:
------------
preg_split fails on some specific input, which seems to be caused by a
subpattern. If in the testcode I reduce the length of the string in between
the middle [..], it works fine.
Test script:
---------------
<?php
$input = '[a][012345678901234 ][a]';
// first match a [, then anything but spaces, end with ]
$tokens = preg_split('/\\[([^\\s]*)*\\]/U', $input);
print_r($tokens);
$tokens = preg_split('/\\[[^\\s]*\\]/U', $input);
print_r($tokens);
Expected result:
----------------
Array
(
[0] =>
[1] => [012345678901234 ]
[2] =>
)
Array
(
[0] =>
[1] => [012345678901234 ]
[2] =>
)
Actual result:
--------------
Array
(
[0] =>
[1] => [012345678901234 ][a]
)
Array
(
[0] =>
[1] => [012345678901234 ]
[2] =>
)
