Description:
------------
PHP Error appears after restarted the IIS under Windows. The problem of "Invalid access to memory location." is reported when using the php ext although only running phpinfo().

Reproduce code:
---------------
(The bug is produced by running most of the scripts.)

Expected result:
----------------
No Error is expected.

Actual result:
--------------
Actually when I turn off the exif extension, the IIS and PHP are turned back to normal. No more "Invalid access to memory location." occurred. Please check out the php_exif.dll for any bugs.

ISAPI is being used with IIS 6.0 in Windows Server 2003 STD
Slow computer P3-733 is used with 512MB PC133 RAM
Only phpinfo() is running.
Page is viewed in any computer with IE 6.

Until now, this only happened when turning php_exif.dll on in PHP EXT.
Thanks!!

Does this happen if you don't use ISAPI but use the FastCGI instead (which is the preferred SAPI to use with IIS anyway..) ?
 [2007-09-09 11:09 UTC] php at littlekp dot ddo dot jp 
I havent tried as I preferred to use ISAPI rather than CGI (php.exe).
CGI seems unsafe in IIS and hard to configurate.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

same problem here.
when activated the exif extension 
php gives an error: Invalid access to memory location. 

when the session.save path is qouted  to disable it, php works once again.

Same thing here on a fresh install of PHP 5.2.5 on IIS 6 (Windows Server 2003) in ISAPI mode. No messages sent to log file or NT Eventlog. Disabling EXIF cleared error.

I just had this problem (exact same error) after installing EXIF also (IIS6, PHP 5.2.4).  Restarting iis did nothing.  However, a reboot thankfully made it go away, before I had to download all the tools to do the backtrace.

encountred same problem winodws 2003 php 5.2.11 ISAPI IIS 6

resolved by checking permissions on these directories

upload_tmp_dir="C:\Temp"
session.save_path="C:\Temp"
error_log="C:\temp\php-errors.log"

Try using the FastCGI SAPI. The ISAPI is not supported anymore (by php.net or MS).
