I disabled all extensions, same crash.

As soon the thread exist how called the ISAPI extension the server crashes. This may be diffrent on each server implementation, and some server my only exit the isapi thread when thy a shut down. And the IIS may report not a error when shutting down at all.

Bugreport 27741 and 27751 report simular or even the same crashes. All when they updatet from version 4.3.4 to 4.3.5.

Hallo,

i'am again.

I just downloaded the sourcecode from php 3.4.5 and find the followring:

Calling "_endthread();" in the "HttpExtensionProc" will always kill the thread on the server how called the "HttpExtensionProc" ! That looks to my as a huge bug. I mean the php modul can not just kill a thread on the server, or do i see this wrong ? (than i quit my job as software developer)

Could you please try replacing php4isapi.dll with the one in 4.3.4?

With the isapi dll from version 4.3.4 is now diffrent, php crashes. 
Useing the "php4isapi.dll" from version 4.3.5 and the "php4ts.dll" from version 4.3.4 does NOT crash, and everything works fine. So the error must be in the "php4ts.dll"

So i think the "php4ts.dll" raises some kind of exeption, what is catched in the "php4isapi.dll", how is than terminating the thread (on the server) how called the "HttpExtensionProc" function.

Do you have any Zend extensions being loaded in php.ini? 

No, i do not have the Zend extensions loaded, i don't have any extension loaded right now.

Could you please try http://downloads.php.net/ilia/php-4.3.6RC1-Win32.zip

No still crashes. and it still is in the "php4ts.dll". Useing the ISAPI DLL with a older "php4ts.dll" is works.

I would spend the time and help you find the error, but i can't compile the source code with my VS 6.0 SP4 or VS.NET 2003 It looks for some Header files i don't have.

#include "arp/inet.h"
#include "zlib.h"
#include "sys/cdefs.h"
#include "netdb.h"
...

Hallo,

i compiled the php source and run it in debugger of the webserver. I'am not sure if i'am right but i found a few strange things.

1.) If the thread on the server exist how called the "HttpExtensionProc" the DLLMain function in the "php4isapi.dll" is called and runs this code.
    case DLL_THREAD_DETACH:
	ts_free_thread();
	break;

after that the thread exit procedure in windows it self crashes. I have to tell you the webserver runs every call to the "HttpExtensionProc" in his own thread, so that DLL_THREAD_DETACH: is called after evry php call.
Because the same "php4isapi.dll" with older "php4ts.dll" version work, i think the error must be somewhere "ts_free_thread();" funktion.


To other messager showed in the debugterminal up:
c:\work\php-4.3.5\zend\zend_hash.c(544) : ht=0x014f0820 is already destroyed
c:\work\php-4.3.5\zend\zend_hash.c(108) : Bailed out without a bailout address!

I don't now if they have something todo with it.

If you need mor information or what every, "i'll be back" on monday morning GMT+0200

Just tried version 4.3.6 RC2 the error still exist.

Please try using this CVS snapshot:

  http://snaps.php.net/php5-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5-win32-latest.zip

And make sure you don't have ANY old PHP related dlls _anywhere_ in your system _before_ you install the snapshot!!

For Windows:
 
  http://snaps.php.net/win32/php5-win32-latest.zip

This works. ISAPI Modul loadet, and MySql extension and IMAP extension enabled. So far no crash. I was running "phpmyadmin" and "phpkit" and your own app.

What ever is crashing 4.3.5 - 4.3.6 is fixed in php5 RC2-dev

So please fix it on 4.3.6 too.

with 4.3.6 RC4-dev the bug is fixed. There are no crashes so far. If someone of the php people likes to close this thread he can do it.

closing (btw, you can do that yourself too)
