I needed to use modsecurity so I compiled nginx and modsecurity.

Modsecurity was compiled with options: ./configure --enable-standalone-module

nginx with: ./configure --add-module=../modsecurity-2.8.0/nginx/modsecurity/

When I try to test my configuration I have this:

[root@nginx1 nginx]# /usr/local/nginx/sbin/nginx -t
Segmentation fault

from message logs:
Jun 4 13:57:43 nginx1 kernel: nginx[12229]: segfault at 410 ip 00007f9088569a32 sp 00007fffc90ccf58 error 4 in libc-2.12.so[7f90884e0000+18b000]

Update: it seams it a modsecurity problem, copiled without it (./configure --with-http_ssl_module) work just fine...
