Not a security bug; remove flag.
Hi, i`m not an expert in debugging, but it looks like the segmentation fault is related to /usr/lib64/apache2/modules/mod_ssl.so. Is it a bug?

With openssl-0.9.8b the error seems to be gone...mod_ssl works fine now. (unmask/emerge dev-libs/openssl-0.9.8b & emerge apache again)

Upgrading to (masked) apache-2.2 fixed this issue for me.

Could you try this patch: http://mastermind.ev6.net/code/peruser.patch It helped me. Also read this: http://www.telana.com/pipermail/peruser/2007-March/000746.html
Guess this is fixed with a recent version of apache ? (Like apache-2.2.4-r6 for example)
