httpd -l works fine but httpd -f httpd.conf results in a Floating point exception (core dumped) before serving any pages.

I added --with-mysql=/usr/local and have also tried with the buildin mysql-support. I have tried with apache 1.3.9, 1.3.12 and 1.3.14.

php.ini is the dist-file, only strange thing is I already is running php3.14 on port 80 and is trying to start php4 on port 81. The mysql installation is rather ancient (3.22.25), apache never gets to write anything in the errorlog befor exiting.
