Previously when we've seen segfaults, they've been due to openssl being
linked into two different parts of the system, and not interacting well
together.  I've seen a previous report of this, but have been unable to
replicate.  At a guess, is your ExternalAuth connection using ldaps://,
are you using mod_perl, and is your Apache listening on https:// ?

The short-term fix is to switch to fastcgi, from mod_perl.
