Problem - apache seg faults on startup, because of the php4 module compiled with --with-mysql - if php is compiled --without-mysql it loads fine.

Details:

MySQL 3.23.38, Apache 1.3.20 and PHP 4.0.5 on a Slackware Linux 7.1 system running the 2.4.0 kernel with glibc 2.1.3.

MySQL was compiled from source and is running fine.
I have added /usr/local/mysql/lib/mysql to /etc/ld.so.conf and activated it before compiling either apache or php.

apache was compiled with:
CFLAGS="-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64" ./configure \
--prefix=/usr/local/apache --verbose \
--enable-module=so \
--enable-module=auth_anon --enable-shared=auth_anon \
--enable-module=auth_db --enable-shared=auth_db \
--enable-module=expires --enable-shared=expires \
--enable-module=headers --enable-shared=headers \
--enable-module=info --enable-shared=info \
--enable-module=log_agent --enable-shared=log_agent \
--enable-module=log_referer --enable-shared=log_referer \
--enable-module=rewrite --enable-shared=rewrite \
--enable-module=usertrack --enable-shared=usertrack \
--enable-module=vhost_alias --enable-shared=vhost_alias \
--enable-shared=access --enable-shared=actions --enable-shared=alias \
--enable-shared=asis --enable-shared=auth --enable-shared=autoindex \
--enable-shared=cgi --enable-shared=dir --enable-shared=env \
--enable-shared=imap --enable-shared=include --enable-shared=log_config \
--enable-shared=mime --enable-shared=negotiation --enable-shared=userdir \
--enable-shared=setenvif --enable-shared=status

Then php was compiled with many settings, last of which is:
./configure --with-mysql=/usr/local/mysql --with-apxs=/usr/local/apache/bin/apxs --enable-track-vars --enable-debug

I coredumped /usr/local/apache/bin/httpd -X and then ran
gdb on it & the coredump.  The backtrace revealed this:

Any ideas?
