Description:
------------
I am running PHP on IIS7 and when I try to use the HOST section, I get a 500 Internal Server error every time. Here is the section implementations that I have tried:



Reproduce code:
---------------
---
From manual page: ini.sections
---
[HOST=intranet.pridedallas.com]
track_errors = Off
html_errors = Off
session.bug_compat_42 = Off

AND

[HOST=intranet]
track_errors = Off
html_errors = Off
session.bug_compat_42 = Off

Actual result:
--------------
HTTP Error 500.0 - Internal Server Error
C:\PHP\php-cgi.exe - The FastCGI process exited unexpectedly

Thank you for your bug report.

Is there additional information in the IIS or PHP error log?
 [2009-07-02 16:35 UTC] keithdavis at pridedallas dot com 
I am unfamiliar with the error_log. I found it in the php.ini file, but enabling it and setting the file name to php_errors.log, did not seem to do anything. Even when I disable the HOSTS section, still not error_log created. Where is this supposed to reside? 

Nothing in the IIS logs during this crash.
 [2009-07-02 19:37 UTC] keithdavis at pridedallas dot com 
Ok, I figured out the error_log thing. I cleared the log. Enable the HOST section, restarted IIS and loaded a page. IIS crashed with the 500 error. Nothing written to the log.
 [2009-07-02 21:53 UTC] jani@php.net 
Does it actually _crash_ ? 500 internal error isn't necessarily sign of 
a crash..
 [2009-07-02 21:55 UTC] keithdavis at pridedallas dot com 
Ok, well, it's a 500 error and there's nothing in any error log. Call it what you like. :)

It does under certain circumstances, for example using [HOST=localhost:8080]. Trying to figure out hwow to debug the .y :)

It says to use MSVC6, but I am using the VC9 version of PHP, so shouldn't I use Visual C 2008 for this? Will Express work or do I need to do the without compiler method?
 [2009-07-06 22:42 UTC] keithdavis at pridedallas dot com 
I apologize, but I am unfamiliar with the backtrace process and I don't understand how to do this. If you can give me more specific instructions. I don't have VC (just VC express) and it doesn't appear that this can be used. I have tried with the Debug Diagnostics method, but either I am not doing it correctly, or this is a crash that is not being detected.
 [2009-07-06 22:55 UTC] pajoye@php.net 
I already provided one. But if you can provide one for your case, see http://bugs.php.net/bugs-generating-backtrace-win32.php

Maybe you catched another issue than the one I used.
 [2009-07-06 23:13 UTC] keithdavis at pridedallas dot com 
I didn't even see that. I tried to follow those directions. Hopefully, they can figure it out from yours.
 [2009-07-07 01:16 UTC] scottmac@php.net 
I tried to reproduce this on OSX and Linux without luck.

The error looks like it's in main/php_ini.c from the backtrace, but I'm not sure whats up with the zval.
 [2009-07-07 09:34 UTC] pajoye@php.net 
I was not able to reproduce the HOST issue. The backtrace does not crash in php_ini.c but before.
 [2009-10-06 21:20 UTC] keithdavis at pridedallas dot com 
FYI, this happens with the PATH section enabled as well.
 [2009-10-06 21:56 UTC] keithdavis at pridedallas dot com 
And it also happens for me on IIS6 (Server 2003.)
