More information:
I tried to access the page, test.php, with the reproduce code by using
telnet command. The result was the followings.
-------------
prompt> telnet <IP> 80 # I wrote it.
Trying <IP>...
Connected to <IP>
Escape character is '^]'.
GET /test.php HTTP/1.0 # I wrote it.
# I pushed an enter key.
Connection closed by foreign hosts.
prompt>
#I substituted '<IP>' for a real IP address.
-------------
So I found that it aborted without any message.

I know that it depends on platforms. I use PHP on Windows XP Pro,
Apache2.0.46 and PHP4.3.3. It also appears on PHP4.3.3RC1. A preg_match
with the same regular expression works fine on other platform.
Thank you.

Works fine here on Linux, what locale are you using?

Description:
------------
PHP aborts without any message or runs forever in below case.
Platform: Windows XP Pro, Apache2.0.46, PHP4.3.3
For example, in preg_match('/a(?:.)+z/',$str,$match), the length of
string matched between 'a' and 'z' is more than approximately 1KB. It
always appears. According to the length, PHP aborts without any message
or runs forever.
It also appears in preg_match('/a(?>.)+z/',$str,$match), but does not
appear in preg_match('/a(.)+z/',$str,$match) and
preg_match('/a.+z/',$str,$match).
Actually, I want to use
preg_match_all('/<tr[^>]*>((?>.(?!<\/tr>))+.)<\/tr>/is',$str,$matches)
and so on.
Reproduce code:
---------------
$str =<<<EOD
a

z
EOD;
preg_match('/a(?:.)+z/s',$str,$match);
echo $match[0];
// It cannot reach the 'echo $match[0];'.
Expected result:
----------------
