Does valgrind show you anything useful?
A segfault somewhere in OpenLDAP doesn't look like PHP problem so far.

This is my php-4.4.4 --without-mysql variant. The production apache
module I normally use obviously has MySQL support
Using browser to test MySQL connections

Now I've implicitly rebuilt php-4.4.4 --without-mysql. Installed and
tested that indeed MySQL connections fail, and they do.
Still Segmentation fault on ldap_connect.

Right I've now compiled MySQL from source code. I'm using the
mysql-5.0.18-src RPM as this matches exacly the binary RPM that comes
with SuSE 10.1. Configure MySQL:
./configure --prefix=/usr --without-yassl --enable-thread-safe-client
--with-gnu-ld --without-server
--with-named-curses-libs=/usr/lib64/curses/libcurses.a
--without-yassl I believe is the significant part. Built & installed
Checked the libraries & header files are in the right place:
ldconfig
Re-built php from scratch. Configure as before. Installed & restarted
Apache2. Same result.
Segmentation fault on ldap_connect. Please help.

Upgraded all 3 MySQl packages to version 5.0.24a. Re-built php-4.4.4
from scratch by deleting top level directoty and re-extracting tar
file.
Ran configure as beforw. Built no problem.
make install
/etc/init.d/apache2 restart
Same problem when using ldap_connect:
[Wed Sep 20 10:38:25 2006] [notice] child pid 21744 exit signal
Segmentation fault (11)
I can try and get a backtrace if you think it would help. Never done
this before but the instructions seem straightforward.
