Description:
------------
In each call to the HttpExtensionProc in the ISAPI Modul of PHP a
Windows exception 0x000006A6 is raised. I debuged it back to the that
line of sourcecode: DeregisterEventSource(PW32G(log_source));
Line 64 in file wsyslog.c

After stepping into that line the exception 0x000006A6 is raised.

The Stackframe looks like that:
php4ts_debug.dll!closelog() Line 64
php4ts_debug.dll!zm_deactivate_syslog (....) Line 125
php4ts_debug.dll!zm_deactivate_basic (....) Line 1243
php4ts_debug.dll!modul_registry_cleanup (....) Line 1168
php4ts_debug.dll!zend_hash_apply (....) Line 701
php4ts_debug.dll!zend_deactivate_moduls (....) Line 678
php4ts_debug.dll!php_request_shutdown (....) Line 982
php4isapi.dll!HttpExtensionProc (....) Line 899

I have a screenshot avalible with all the details of the stackframe.

In normal operation mode, the only sign will be only a memory leak. 

The problem was NOT pressent in version 4.3.10.
But PHP version 5.0.4 has the same problem.
