Building php with...

./configure --with-apxs=/usr/local/apache/bin/apxs \
--with-config-file-path=/server/httpd/conf \
--enable-c9x-inline \
--without-mysql \
--enable-shared=all \
--with-oci8=$ORACLE_HOME 

with ORACLE_HOME correctly set. I Have Apache 1.3.12 compiled with:

/usr/vac/bin/cc -qlibansi -qansialias -lpthread

php is built with the same compiler/options

Compiles ok and apache starts ok. The header in the log states php 4.0.2 is loaded.

I have a test page...

<?php
phpinfo()
?>

When I try to load the page in a browser the apache instance seg faults.

I have built php exactly the same but minus the oci8 support and it works fine.

Any answers.

If this adds anything to the case.

Awaiting feedback on this bug report!

Does this happen with PHP 4.0.4 ? 
Or with latest snapshot from http://snaps.php.net/ ??

Haven't tried a newer version of PHP. What exactly would be the point of this exercise? Is there a specific change or area of change in the later versions that could have an influence? If not then trying a newer version won't reveal anything about the problem.

I haven't tried the snapshot either. To be honest I don't know what a snapshot is. I've searched the php site for info about snapshots and trawled through the FAQ. I've even searched the Zend site. There's nothing to be found. In the absence of info I don't want to waste my time downloading something that I know nothing about.

There have been a lots of fixes in both PHP and Zend after 4.0.2 was released.

Another thing, did you set the environment variables (for Oracle) before starting
apache? Please check: http://www.php.net/manual/ref.oci8.php
