Running PHP 4.2.2 (binary download) as a servlet under Caucho Resin 2.0.1.  The application I'm trying to run is OBM 0.5.2 (www.aliacom.fr).  Following is the error that shows up in Resin's stdout.log.

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC=0x9599A40
Function=zend_hash_index_update_or_next_insert+0x20

I have also a related problem.
I'm usign Windows 2000 Server SP2 (All hotfixes).
The application is SquirrelMail version 1.2.7.

The server runs OK for a while, until, it doesn't respond. And the server log show:

The HTTP server encountered an unhandled exception while processing the ISAPI Application '
php4ts!zend_strndup + 0x2B
 + 0xA05C16DC
'.

The microsoft page does not exist, but I am running Win2k IIS/PHP-4.2.2 here, and have not seen this issue.  I consider that bogus.


As for the initial report running as a servlet, I haven't any experience with this webserver... nor do I know if PHP really even works with it (non-documented).  Can you place the error message from hs_err_pid1892.log in the bug report though as well?
 [2002-08-17 11:46 UTC] mario dot cormier at polyester dot com 
The log file contains *exactly* the same information I pasted in the original submission.  I would not think Resin per se is the problem, as I managed to see the output of 
<?php phpinfo(); ?> with it.  From my experience, a crash in native code like this one can only result from a bug in the native code or possibly a bug in the JVM.

Just marking as "Open" again...
 [2002-10-28 06:37 UTC] bariou at brasnah dot com 
RH 7.2 Linux 2.4.7.10
PHP 4.2.3
TOMCAT4.1.12
COCOON2.0.3
JSDK1.4.1

It seems to work but .....
I Am enable to run the JAVA extension or PHP as  servlet correctly, for the last test of PHP I try to work with PHP as a servlet. It seems there is a problem with the send () native method of PHP :
(this call is created inside the servlet.java class from php.../sapi/servlet/ ) => 
Public native send(string requestMethod, String QueryString, String pathInfo, String PathTranslated, String contentType, int contentLength, String authUser, boolean display_sourc_mode).

As developed in the the bug id : 16402, I've also place libphp4.so  inside /usr/java/j2sdk1.4.1/jre/lib with the related correction to the LD_LIBRARY_PATH. I understand that JAVA waiting for a php4.so, but it start to work only through a soft link =>
ln -s libphp4.so php4.so

if  I rename directly libphp4.so as php4.so it does not find any php4 in library.java.path

java.lang.UnsatisfiedLinkError: no php4 in java.library.path 

With a soft link , It seems to work  with the following file 

<?php
echo "PHP AS A SERVLET";
$a=2.0*5;
echo $a;
?>
It's OK it works... several time, no problem
on the other hand if I try :
<?php
phpinfo();
?>
The Virtual machine crashes each time.... With the the message than the exception was detected in the native code outside the VM
unexpected Signal: 11 occured at PC=0x4EA8A5BF
Function=zend_hash_index_update_or_next_insert+0x3B
library=......../i386/libphp4.so
Is it a bug in the virtual machine ? I'm circumspect about that ! The ouput is not a well-formed XML tree  ?  But I don't know

I am having an access error as well now, in the latest 4.3.0 release. This under tomcat and windows 2k. The function is not the same as this (zend_hash_index....) I will add the function name when I am able to try this again this evening.
