User Update by: [EMAIL PROTECTED]
Status: Open
Bug Type: Reproducible crash
Operating system: Windows 98
PHP Version: 4.0.6
Description: Apache 1.3.20, mod_ssl 2.8.4, PHP 4.0.4 crashes in CGI mode

Seems like someone else has been having a similar problem (Bug #10904 - I got curious 
as to what the other reproducible bugs were).  My previous comments should help narrow 
this problem down further (and actually make it reproducible).  My guess is that it is 
not only Windows platforms, but possibly even Linux...but that has yet to be proven.  
Right now I'm not in the mood to log into Linux and give myself another headache.  One 
at a time is plenty for me :)

(XiFusion is also for Linux, so it would be interesting to see if Apache fails under 
Linux due to the
Apache->Perl->XiFusion->PHP combo).

The Short Description is supposed to be 4.0.6, although the bug is also in 4.0.4.  
4.0.5 is untested for the bug.

Using the default PHP 4.0.6 package for Win32 (downloaded straight from php.net), I 
have found an interesting combination that causes Apache 1.3.20 to core dump.  My 
objective was to set up an SSL server to seamlessly work with the Xitami webserver, 
Apache is the obvious choice here.

The first thing I did was download and install Apache 1.3.20 for Win32.  Then, I 
applied the patches located in Apache_1.3.20-Mod_SSL_2.8.4-OpenSSL_0.9.6a-WIN32.zip on 
the contributions page of the www.modssl.org site.  Finally, I configured and set up 
the SSL virtual server (both a self-signed and a CA-signed certificate work) and got 
everything working.  I wrote a short Perl script that would call XiFusion with the 
correct parameters:

#!c:/perl/bin/perl

$ENV{"SCRIPT_NAME"} = $ENV{"REDIRECT_URL"};
system "c:\xifusion\xifusion.exe c:\php4\php.exe";

Side Note:  I am the author of XiFusion v2.5 (a wrapper for CGIs under the Xitami 
webserver for ColdFusion and PHP <http://www.xitami.com/xifusion.zip>).

This setup worked fine...sort of.  I have tried everything I can think of to prove 
that PHP isn't the culprit, but it is.  Here is what happens:

1)  The browser connects to the SSL server.
2)  The browser request a PHP page.  Apache sees that PHP extensions are aliased to a 
type, thus it checks out the action it should take.  It then executes the previously 
mentioned Perl script.
3)  The Perl script modifies an environment variable and calls XiFusion.
4)  XiFusion does its thing and executes PHP (I've checked to see if XiFusion or the 
Perl script were the problem and they are not).
5)  PHP then starts to process the page.
6)  ApacheCore.dll for some reason core dumps.  I have no idea why it does this (it is 
somewhat random, but *VERY* reproducible).
7)  The odd thing is is that when I click "Close" on the dialog box, Apache reloads 
and acts like nothing happened...weird (none of the log files show that an error 
occurred either...even weirder).

What is even weirder than all that is if I switch from CGI mode to module mode (modify 
conf/httpd.conf), there is no problem...even under normal Apache 1.3 API.

I've scoured google.com as well as the PHP databases for any solution to this very 
interesting bug.  I've been re-building everything (Apache, OpenSSL, mod_ssl) from 
sources to see if I can improve the situation any.  So far, no luck (no, I didn't 
forget to replace the DLLs in the Windowssystem directory).  I've seen references to 
the
-DEAPI compile option for PHP, so I will try that out tomorrow to see if that helps 
(but knowing my luck so far... :)

This bug is also in PHP v4.0.4.

Pertinent Machine Info.:
OS:  Win98
Dual PIII 500 mHz CPUs
384MB RAM (I try to maintain about 150MB free using RamIdle)
18GB HD (5 GB free on the Win98 partition)

I really want to use the XiFusion wrapper program rather than the module since I can 
get more control through XiFusion than I can through Apache.

Sorry, no gdb backtrace.  My debugging methods are usually lots of good ol' fashioned 
printf statements ;)
