I can confirm that this problem also exists on PHP 5.3.2 on Windows Server 2003
32-bit with IIS running FastCGI. Problem also occurs on WAMP server, Windows 7
64-bit running PHP 5.3.8, Apache 2.2.21 with PHP loaded as a module, not CGI.

Here is the Application Event log entry in Windows Server 2003 when this crash
occurs in my test case above:
Source: .NET Runtime 2.0 Error
Description:
Faulting application httpd.exe, version 2.2.19.0, stamp 4dd6eda8, faulting
module
php5ts.dll, version 5.2.17.17, stamp 4d25fb49, debug? 0, fault address
0x000ea66d.
This source is a little odd, because I have .NET 4.0 Runtime installed. Note
that although I have PHP 5.2.17 installed at the moment, I have experienced
this
with 5.3 as well.

Can this bug's summary be edited to remove "(FastCGI IIS)?" My comment above
shows
that it can be reproduced under Apache as an Apache handler as well.

This error only appears to happen when the offending code is run from a web
server. If I run the offending code directly from the CLI, php never crashes.
If
I run the same code through Apache (via a cURL request), Apache crashes every
other time. My configuration is:
* Windows Server 2003 R2
* Apache 2.2
* PHP 5.3 configured as an Apache handler, not under FastCGI (see
http://www.php.net/manual/en/install.windows.apache2.php)
* The following 2 files:
----------
<?php
// testCrash.php - file #1
$stack = new DOTNET("mscorlib", "System.Collections.Stack");
echo "success";
?>
----------
<?php
// testCrashClient.php - file #2
$endPoint = 'http://localhost/testCrash.php';
$client = curl_init();
curl_setopt_array($client, array(
CURLOPT_FRESH_CONNECT => TRUE,
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_URL => $endPoint
));
$response = curl_exec($client);
curl_close($client);
var_dump($response);
echo 'done';
?>
----------
Use case #1 - run locally, we get no crash:
Steps:
1. Open command prompt
2. Execute:
php.exe testCrash.php
3. Observe that we get the expected resulting output:
success
4. Repeat step 2. Expected result will always be obtained.
Use case #2 - run through the web server, we get the crash:
Steps:
1. Open command prompt
2. Execute:
php.exe testCrashClient.php
3. Observe that we get the expected resulting output:
string(7) "success"
done
4. Repeat step 2.
5. Now observe that we get an error:
bool(false)
done
6. Repeat step 2.
7. Expected successful output is obtained again.
Repeating step 2 will cause the crash every other time. When the crash occurs,
apache's error log gets:

It appears this behavior was intentionally introduced by WEZ back in 2003.
http://svn.php.net/viewvc/php/php-src/trunk/ext/com_dotnet/com_dotnet.c?r1=137794&r2=146718
I don't know what problem he was trying to fix back then, so I'm not sure of
the implications of adding these two lines back. But if you are using fastcgi,
then jeyb88 is absolutely correct: this will crash every other time the code is
run.
My repro is even simpler than jeyb88's. I don't even have to call any methods
on the .net object. I have a 1 line php file that calls the "new" against my
.net class:
<?php
$class1 = new DOTNET("moo, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=14ba337483520f7a", "moo.Impersonation");
?>
The constructor for my .net class is empty:
[ComVisible(true),
ClassInterface(ClassInterfaceType.None),
Guid("53C74B01-EC09-45a4-A741-42727858B2A1")]
public class Impersonation
{
public Impersonation()
{
}
// more code follows
When I first browse to the page, it (correctly) shows nothing. Then I hit
refresh, and I get the "FastCGI process exited unexpectedly" 0xc0000005. If I
hit refresh again, the page again (correctly) shows nothing, next time, fastcgi
AVs again.
I am using php 5.3.3, Windows Server 2003, and I have tried both .Net 2.0 and
.Net 3.5.
The pattern here is easily reproducible, causes an unrecoverable access
violation, and there is no workaround. A fix here would be greatly appreciated.
