On a Solaris 10 server I installed Apache2 (v2.2.20), PHP5 (v5.2.1), and all dependencies with packages from : http://unixpackages.com (the new sunfreeware.com).
Now apache is running, and doesn't generate errors at startup. The probleme is when I ask the server with a browser I get an ERR_EMPTY_RESPONSE.
In logs, each time I ask the server I get this error :
child pid "PID" signal Segmentation fault (11)
It seems coming from PHP while there's no error when deactivate it in httpd.conf, but I can't find where.
Using the last version of PHP available on unixpackages.com (v5.3.6) and forcing some library paths during install solved the problem. It seems that older version don't works with Apache v2.2.20.
Thanks a lot for your answers even if they weren't very helpful.
