Sorry, the discription is misleading. Requesting a page via HTTP_S_ works. Via plain HTTP it segfaults.
Does this happen on a specific page, or on every page? If every page: What (if any) changes have you made to the configuration? Please attach any relevant configuration (i.e. files you have changed) If a single page: Please attach the file that it's segfaulting on. Also, a gdb backtrace might be useful as well.

http://httpd.apache.org/dev/debugging.html
actually, looking closer at those instructions for getting a backtrace, there's a few minor differences for Gentoo. Instead of 'gdb httpd' do 'gdb /usr/sbin/apache2'. The run line needs to be a bit different: run -X -D DEFAULT_VHOST -D PHP4 (etc etc, the stuff from APACHE2_OPTS).
Ok, thanks.

Without debugging symbols a backtrace is useless, as it's not possible to know what crashes. :) To obtain debugging symbols you also need to add -ggdb to the CFLAGS, a very good general documentation on backtraces on Gentoo can be found at: http://www.gentoo.org/proj/en/qa/backtraces.xml Best regards, CHTEKK.
