This sounds more like a problem with mod_auth_pam. Nagios just looks at
the HTTP environment variable REMOTE_USER to determine who is logged in.
That variable is set by Apache via whatever auth method you use. As you
stated, Apache native mod_auth works fine. How do you know that you're
getting authenticated correctly? Based on the information above it seems
that the segfault is probably happening in the time between the Auth and
when the CGI is executed or during authentication.
