First of all, it's a PCRE library problem.
And it's fixed in newer PCRE versions which are bundled in recent PHP
releases.

This is also reproducible in command-line php.exe
PHP 4.4.4
PHP 5.1.6 (!)
Cannot reproduce on PHP 5.2.0.

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).
