Hello, 

Apache crash on windows platform when i use syslog functions ( openlog, syslog, closelog) and exit().

the script is:
1: <?php
2: define_syslog_variables();
3: openlog("Test", LOG_PID | LOG_PERROR, LOG_LOCAL0);
4: syslog(LOG_WARNING,"Essai de log");
5: closelog();
6: exit();
7: ?>

if i comment line 5 and 6, it's works fine.
if i comment line 3, 4, 5 , apache crash after few reload or navigation between index page and this script.
if i comment line 6, apache crash in the same case as above...

config:
 w2k pro sp2 
 apache 1.3.22 ( start in commmand line or as service )
 php 4.1.1 + ldap + oci8 (8.1.7)

 win nt 4 sp 6
 apache 1.3.22
 php 4.1.0 + ldap + oci8 (8.1.6)

Does this also happen if you only use the CGI version on command line and as less modules (i.e. no ldp/oci8/whatever) as possible?

Crash appear with the php module, not with cgi version.
with module and without extensions, apache always crash...

So this bugs is related to apache module.
I don't test with php 4.1.2 and on linux, it seems to be ok.

platform : apache 1.3.24 / php 4.2.1 / w2k SP2

I test on php 4.2.1 and there are some difference.

The exit function seem to not cause bug, but the closelog crash apache (drwatson is started...). This appear when i reload one or two times the script.
all works fine when i comment closelog. 

No problem on linux

I cannot replicate the crash.

However, there is a definate problem with the docs for openlog() functions. On win32 LOCAL_LOG0 through LOCAL_LOG7 are not avaliable. In fact the openlog line in the example returns a warning about the 3rd parameter being invalid.

The openlog facilities should be better documented, mentioning which are *nix specific, win32 specific and which are common.

Actually that's LOG_LOCAL0 through LOG_LOCAL7 that are not avaliable. I made a typo in my previous comment.

i get the same crash with php 4.2.3.  without exit call at end of script.

Ok for the documentation error

i rerun test with php 4.30pre1 and i see this version is more stable. apache doesn't crash, but i get popup message like this : instruction at 0x100d4ebd ..... memory could not written.

but the hexa value seems to change if i run apache in command line or like service, or sith a different version (like 2.0.43).

This information has been documented in a couple places:

http://cvs.php.net/cvs.php/phpdoc/en/reference/network/functions/syslog.xml
http://cvs.php.net/cvs.php/phpdoc/en/reference/network/functions/openlog.xml

Thanks for the report :)
