Calling php 4.02 (through [O'Reilly] WebSite 1.1) always gets Windows page fault failure "...invalid page fault in module php4ts.dll...."

Php.exe starts OK from a DOS box command line, with no errors reported; e.g., 
   C:>php -i

but when a PHP page is called through the web server the page fault error occurs.  Reproducable every time.

No scripts run at this point; all attempts fail.

My installation is "default" as downloaded.  Only local path info is changed in the .ini file.  (Happy to send it if that's useful to you.)

FYI: This setup is just the same as what I have for php3.  Php3 runs OK and interprets pages as expected.   

FYI: This PC is an old AMD '586 (486 clock doubled), sp2 Win 95.  (Are you looking for Pentium specific stuff?)

FYI: the dump report from Windows:
