Here is the code that crashes:
   global $HTTP_COOKIE_VARS;
   $cvar=$HTTP_COOKIE_VARS["user_name"];
   ...so far, everything works OK.  But after some more code that uses $cvar, like: if (empty($cvar)), etc, PHP crashes and I get Page Not found!
   I was able to fix this, by simply adding unset() like this:
   global $HTTP_COOKIE_VARS;
   $cvar=$HTTP_COOKIE_VARS["user_name"];
   unset($HTTP_COOKIE_VARS["user_name"]);

Thank you for this bug report. To properly diagnose the problem, we

Sorry, my mistake.  It wasn't a PHP bug, but an error in my coding!  There was a loop where a function called itself again and again infinitely until the script simply quits... Sorry about that, now I have fixed it.  Please erase this bug report. Thank you.
