when I try to restart Apache after installing PHP4_mod (libphp4.so), it dies:

/usr/local/apache/bin/apachectl[124]: 61546 Segmentation fault(coredump)


configure was run as follows:

./configure --with-oracle \                  
--with-apxs=/usr/local/apache/bin/apxs \     
--with-oci8 \                                
--enable-discard-path \                      
--without-mysql \                            
--enable-track-vars 


I tried this with Oracle 8.1.7 and 8.1.6, and also with PHP 4.0.4, same result.

do I do something wrong?

Could you please generate a GDB backtrace?
First reconfigure with --enable-debug of course.

rm config.cache
./configure .. <your options + --enable-debug>
make clean
make 
make install


and then try generating the backtrace.

Which Apache version is this? 
And obviously your libphp4.so is not configured
with --enable-debug..

Does it work without Oracel support?

here is the information you asked for. I did my best to configure php with --enable-debug, but I am not sure if I produced the backtrace correctly: gdb <path/to/httpd> <path/to/core>
As you can see, I configured without oracle support, but I still get the segmentation fault


Apache version: Apache/1.3.12 (Unix)





first lines of config.status

#! /bin/sh
# Generated automatically by configure.
# Run this file to recreate the current configuration.
# This directory was configured as follows,
# on host vela:
#
# ./configure  --with-apxs=/usr/local/apache/bin/apxs --enable-debug --enable-di
scard-path --without-mysql --enable-track-vars
#



some lines from the output of configure:

checking for Apache module support via DSO through APXS... yes
checking for Apache 2.0 module support via DSO through APXS... no
checking whether to include debugging symbols... yes

This should be fixed with PHP 4.0.6, please try the 
latest release candidate:
