PHP has been compiled as CGI using the follwing configure options:

./configure  --enable-force-cgi-redirect --with-gd --with-ttf --with-mysql --disable-display-source --with-config-file-path=/etc --with-ldap

when running it against a script containing only this line:

<? include "categories.inc"; ?> 

and "categories.inc" starting with:

<TD>
<?   $dbhost="XXXXXX";
   $dbname="XXXX";
   $dbuser="XXXXX";
   $dbpwd="XXXXX";
   print "$REMOTE_USER";
   $mysql=mysql_connect($dbhost, $dbuser, $dbpwd);
   mysql_select_db($dbname, $mysql); 

...

php segfaults:

We are sorry, but can not support PHP 3 related problems anymore.
Momentum is gathering for PHP 5, and we think supporting PHP 3 will
lead to a waste of resources which we want to put into getting PHP 5
ready. Ofcourse PHP 4 will will continue to be supported for the
forseeable future.
