Since version 4.1.2 I haven't been able to upgrade my PHP as everytime I try to start httpd I get segmentation fault.

I've compiled PHP with following line:

"./configure --with-mysql=/usr/local --with-jpeg-dir=/usr/local --with-png-dir=/usr/local --with-mm=/usr/local --with-openssl=/usr/local/ssl --with-zlib=/usr/local --with-freetype-dir=/usr/local --with-gd=/usr/local --with-pdflib=/usr/local --with-apache=../apache_1.3.26 --with-curl --with-imap-ssl "

And Apache with:

"./configure --prefix=/usr/local/apache --activate-module=src/modules/ssl/libssl.a --activate-module=src/modules/php4/libphp4.a
--enable-module=so"

Strace from "httpd":

So it's curl that is causing it..you should propably check
that you're using SAME ssl libs for all those which use them. And if that did not help, try remove the --with-openssl from your php configure line.

I removed the --with-openssl option from PHP configuration and now it's working. Thanks a lot for your quick and accurate response. :)
