Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

It looks pretty much like a problem of PCRELib, but I can't tell
anything for sure without a backtrace.

Version 4.4.4 still has this problem :( If I run this script on version
4.3.11 (and other 4.3.x versions) - all works fine, but version 4.4.0
and all versions after it has this bug (on Windows! not Linux).

I have confirmed this problem on another box, this one running XPSP2 /
IIS like the original poster. I don't have a Linux environment with
4.4.2 on it to test that but I hope to shortly.

I can try running a trace but I'm a total noob with that kind of stuff.
I don't see a debug version of PHP 4.4.2 on the snaps page -- just one
for 5.x and 6.x. I tried using the Win32 debug download as referenced
in bug #37188 (see 25 Apr) but couldn't get it to work. Any suggestions
where to get a debug version?

Thanks for your help!



[2006-05-15 21:26:43] dimox at inbox dot lv

Yes, its works on Linux. This bug is Windows only.
On Apache/1.3.29 (Win32) PHP/4.3.10 this code works fine too.

What information I can provide, except backtrace?



[2006-05-14 12:28:11] [EMAIL PROTECTED]

Works perfectly fine on Linux.
Please provide more information.

I have used Dimox's code on a Windows 2000 server running IIS and PHP
4.4.2 and have reproduced the problem. The regular expression commands
on this server combination seem to be susceptible to crashing like
this.

Can I get trial version of MSVC6? If it exist, can you add link for me?
I'm only web-programmer and I has no tools for C++
development/debugging. 

Maybe you can run file test_bug.php on your oun PC with this tools and
generate this debug backtrace?

While i symlificate the code i forgot to remove \%\> from example and
posted text for parsig was too small to cause error. I found, that
block content must be more tan 1330-1360 simbols to couse script crash
- until this values it works fine! I increased all "memory size" values
in php.ini and in the code, but problem still exist.

Description:

Regxp couses PHP script crach on Windows. On Linux Server it works
fine, but I use Windows server on my PC for development. 
I try this code on my own PC with Apache/1.3.34 (Win32) PHP/4.4.2 and
on another PC with Apache/1.3.34 (Win32) PHP/4.4.1. On my PC this code
souses Apache crash, but on another PC this code couses only script
crash. I looking information about this bug anywere, but can't find
anything useful, except http://bugs.php.net/bug.php?id=27735. I try
with logs disconnection, but it doesn't change anything. 
Help ...

Reproduce code:
---
$regex =
'/block\s*name=\"([^\"]+)\"\s*\%\>((.(?!(block\s)))+?)\blockend/is';
while(preg_match_all($regex, $text, $block_matches, PREG_SET_ORDER)){
...
}

Expected result:

$block_matches array with results of regular expression matches. I need
in this to parse blocks like 

block name="name1"
  something
block name="name2"
  something else
  ...
blockend
blockend

Actual result:
--
"Server not found" or "The page cannot be displayed" in browser. 
After simplification of code to:
 
$regex = '/block\s*name=\"([^\"]+)\"\s*\%\>(.+?)\blockend/is';
while(preg_match_all($regex, $text, $block_matches, PREG_SET_ORDER)){
...
}

all works fine(remooved lookahead assertion). If i add () around the
'.' - script crash again.

$regex = '/block\s*name=\"([^\"]+)\"\s*\%\>((.)+?)\blockend/is';
