Bug description:  PHP has encountered an Access Violation

Description:
------------
This is a bug that also occured in PHP5 RC3 as referenced here:
http://bugs.php.net/bug.php?id=28799

The bug system has also reported this as an issue with earlier versions of
PHP.  If it is not prudent to open a similar bug issue for new final
release versions, then by all means this should be closed.

The problem:

The IIS6 server will randomly throw an error like: PHP has encountered an
Access Violation at 017AE084

Alternatively, and even more rarely, PHP will throw fatal errors:  

Fatal error: Cannot redeclare class gfunc in
D:\htdocs\include\global_functions.php on line 2

-- or --

Fatal error: Call to undefined function OCILogon() in
D:\htdocs\include\classes\DatabaseHandler.php on line 45

The gfunc class is only included once using the include_once() directive. 
OCILogon() is part of the oci8 module, and obviously doesn't seem to get
included every few reloads.  The DatabaseHandler is just a simple
interface for passing SQL queries back and forth, which references most of
the oci8 functions.

There is no consistancy with these errors.  A standard page in my
environment makes various oci8 queries, and uses the PHP5 XSL DOM
transform (XML->HTML output).  Smaller pieces of code that exclusively
make use of these features do not seem to crash after several consecutive
reloads, however, larger more complicated applications will crash every
few page reloads and then work the next few.

Actual result:
--------------
PHP has encountered an Access Violation at 017AE084
