Using PHP as a loadable module. Apache/1.3.12 
Configure options:
./configure --enable-static --with-apxs=/usr/local/apache/bin/apxs \
--enable-force-cgi-redirect --enable-calendar --enable-dbase \
--with-gd=/usr/local/ --with-jpeg-dir --with-xpm-dir --with-jpeg-dir \
--with-ttf --with-t1lib --with-mysql=/usr/local/mysql --with-mm \
--enable-trans-sid --with-regex=system --with-zlib \
--enable-inline-optimization --enable-memory-limit \
--with-gettext

After running the following script

<?
session_start();
phpinfo();
?>


The zend credit section says:

This program makes use of the Zend scripting language engine:

If I take out session_start() everything appears without problems.

Can send url by email. I don't want to post it here since phpinfo() displays a lot of server information.  


I just tried rebuilding PHP using:

./configure --enable-static --with-apxs=/usr/local/apache/bin/apxs \
--enable-trans-sid --without-mysql --enable-session \
--without-gd

Same problem applies.
