Here is two link you can try.

This one use --without-gd flag
http://www.hkgonline.net/test3.php

This one use --with-gd flag
http://www.hkgonline.net:8080/test3.php

Just go to each of the link and keep pressing reload button using netscape. You will see the port 8080 one crash from time to time. I use FreeBSD GD-1.8.3 port from http://www.freebsd.org/cgi/ports.cgi?query=gd-1.8.3&stype=all

Source code for test3.php is

<?php

   echo "a";
   cdbconnect(); //call to a function did not define

?>

I think You can try to install the PHP 4.03pl1 in your test FreeBSD system with the flag --with-gd, and see if it does the same error as mine. Here is the config I use

./configure --with-mysql=/usr/local/mysql
--with-apxs=/usr/local/apache/bin/apxs
--with-config-file-path=/usr/local/etc
--with-gd=/usr/local --with-pcre-regex=/usr/local --enable-track-vars

If you can find a fix for it. Please let me know. Thanks

Ok, I found out the problem. Whenever I use --with-gd, it will crash like that. As long as I don't use --with-gd, it works fine. I am using the gd-1.8.3(newest port) for FreeBSD.

Ok, I got a more simple code to reproduce the error. This is the code for test3.php

<?php

   echo "a";
   cdbconnect(); //call to a function did not define

?>

go to http://www.hkgonline.net/test3.php using netscape. You will get that No data error once a while if you keep pressing reload button.
