Foremost, I'm running php 4 final, apache 1.3.12 under Windows 98 first edition.  And I'm having the exact same problem as lloyd@eglean.com.  Apache pops up a little PHP crashed dialog box whenever I try accessing a page.

I'm fairly sure I've confiugred everything properly.  There is no official install for php4 under windows (manual is still only at php3) but I'm 99% sure that everything is configured properly.  The only semi non-standard thing is that my files are all located on the G: drive.  I have apache under g:/web/server/apache, php under g:/web/server/php and the site itself under g:/web/epsilon.

I've got the following (PHP related) lines in httpd.conf:
ScriptAlias /php/ "G:/Web/Server/Php/"
AddType application/x-httpd-php .php .php3 .php4 .phtml
AddType application/x-httpd-php-source .phps
Action application/x-httpd-php "/php/php.exe"
#Action application/x-httpd-php3 "/php/php.exe"

I also tried screwing around with some other variations of the above. Adding full paths, shortening paths, changing slashes this way and that, adding extra slashes, removing slashes, various other little things. (the previous was done only out of desperation.  Do not try this at home, or at all).  Nothing worked.

My php.ini file is fairly standard issue.  A couple minor changes, but no big options changed.  No extensions enabled.  Nada.  

Heres the full error, as if anyone can understand what it means.  Pulling information out of windows crashes is harder than reading the matrix.
PHP caused an invalid page fault in

The only "fix" I've found is to go down to version 3 *shudder*

Thanks!
