Bug description: Case related bug in mb_ereg_* lookbehind
Description:
------------
When using alternation in negative lookbehind in a case-insensitive regexp
with mb_ereg* functions, if the alternatives are of different lengths, the
first alternative is treated in a "case-sensitive" way.
Reproduce code:
---------------
$text='
aA 1
bBb 2
cCcc 3
dDddd 4
';
$pattern='(?<!aa |bbb |cccc )[1-4]';
mb_ereg_search_init($text,$pattern,'i');
$r=mb_ereg_search_pos();
while ($r!==false) {
$match=mb_ereg_search_getregs();
print_r($match);
$r=mb_ereg_search_pos();
}
Expected result:
----------------
Array
(
[0] => 4
)
Actual result:
--------------
Array
(
[0] => 1
)
Array
(
[0] => 4
)
