Comment (by sysrqb):

 It looks like this should do it - I'm testing it now:
 {{{
 diff --git a/src/or/policies.c b/src/or/policies.c
 index 179230b..5b3405b 100644
 --- a/src/or/policies.c

      if (tor_addr_family(addr) == AF_INET6 &&
          (!fascist_firewall_use_ipv6(options) || (pref_only &&

        return 0;
 +  } else {

    }

    return addr_policy_permits_tor_addr(addr, port,
 }}}

 Based on the comment for fascist_firewall_allows_address(), this was the
 intended functionality but I don't see where this happens:
 {{{
  * If we are configured as a server, ignore any address family preference
 and
  * just use IPv4.
 }}}
