I use PHP/FI as a cgi program with Apache and Apache's Action
directive. To stop this bug, I added this to php/fi 2.0b12's main.c
file (around line 45):

#if PHPFASTCGI
        while(FCGI_Accept() >= 0) {
#endif

+       s = getenv("REDIRECT_STATUS");
+       if(!s) {
+           puts("Content-type: text/plain\r\n\r\nPHP/FI detected an internal error. Please inform sa@hogia.net of what you just did.\n");
+           exit(1);
+       }

        s = getenv("PATH_TRANSLATED");


This prevents the script from being called directly via an URL since
that wouldn't set the REDIRECT_STATUS variable. I believe I sent this to
the PHP/FI development list, but I never heard anything from them
(probably because they were going to drop the cgi support).
