Bug description: preg_match() with /u flag corrupts memory
Description:
------------
Seems preg_match with /u modifier corrupts process memory or returns
pointer to nirvana instead of pointer to a string.
Reproduce code:
---------------
<?
preg_match('/(.{0,20})$/us', " ", $m);
var_export($m);
?>
Expected result:
----------------
space
Actual result:
--------------
something like
array (
0 => ' kjwekwjn',
1 => ' wereinoiu',
)
where "kjwekwjn" and "wereinoiu" are random strings with random binary
data (useless to copy-paste them here).
