Summary: PHP-CGI (FastCGI IIS) crashes when creating DOTNET
instance every second time
Status: Open
Type: Bug
Package: COM related
Operating System: XP, Vista, Win 7,Win Server 2008
PHP Version: 5.3.3

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.

Description:
------------
The php-cgi.exe will crash after every second refresh when I make an
instance of the DOTNET class. The Website is hostet via IIS 7 and PHP is
configured as FastCGI module. When I configure PHP on IIS as CGI module
everything works fine, but I can not do without FastCGI. I have made a
change in the com_dotnet.c file in function php_com_dotnet_rshutdown.
The variable called stuff from type dotnet_runtime_stuff will not be
released like in the function php_com_dotnet_mshutdown. So I have added
this two lines to the function php_com_dotnet_rshutdown:
free(stuff);
COMG(dotnet_runtime_stuff) = NULL;
After that I have compiled PHP 5.3.3 with Visual Studio 2008 (VC9) x86
with almost the same configuration like in the PHP 5.3.3 nts version but
without zlib:
configure "--enable-snapshot-build" "--enable-debug-pack"
"--disable-zts" "--disable-isapi" "--disable-nsapi" "--without-mssql"
"--without-pdo-mssql" "--without-pi3web" "--with-pdo-oci" "--with-oci8"
"--with-oci8-11g" "--with-enchant=shared"
"--enable-object-out-dir=../obj/" "--enable-com-dotnet"
"--with-mcrypt=static" "--disable-zlib"
The include and lib files are relative to the configuration file (in the
deps folder). I have earned following error and that's why I have
disabled zlib:
php5.dll.def : error LNK2001: unresolved external symbol compressBound
php5.dll.def : error LNK2001: unresolved external symbol deflateBound
php5.dll.def : error LNK2001: unresolved external symbol deflatePrime
php5.dll.def : error LNK2001: unresolved external symbol gzclearerr
php5.dll.def : error LNK2001: unresolved external symbol gzungetc
php5.dll.def : error LNK2001: unresolved external symbol inflateBack
php5.dll.def : error LNK2001: unresolved external symbol inflateBackEnd
php5.dll.def : error LNK2001: unresolved external symbol
inflateBackInit_
php5.dll.def : error LNK2001: unresolved external symbol inflateCopy
php5.dll.def : error LNK2001: unresolved external symbol
zlibCompileFlags
The error in the com_dotnet.c file was the error, because now with the
new compiled version, fastcgi will not be terminated. Is the zlib
extension necessary for complex php websites like Joomla? Because now
the compiled php version can interpret the sample shown below and it can
interpret simple php scripts, but when I try to load a Joomla site, the
FastCGI will crash. What is wrong with the made configuration? Can you
give me an important hint of how to compile php5.3.3 like in the
original php version?
Best regards, JeyB
Test script:
---------------
<?php
try
{
$stack = new DOTNET("mscorlib", "System.Collections.Stack");
$stack->Push(".Net");
$stack->Push("Hello ");
echo $stack->Pop() . $stack->Pop();
}
catch(Exception $lEx)
{
echo "Error occurred:<br>".$lEx->getMessage();
}
?>
