Maybe I am confused, but we already have apr_pool_join(r->pool, rr->pool); a few
lines above which should do the trick. Is it possible that we have a sub-sub
request here and deal with a table of the main request, so that we have two
generations of pools involved here for which the join trick does not work?

Probably yes. lang.txt is included (first sub) and the lookup_uri comes from
language negotiation.

The scopes are safe (appropriate), but it seems that fast_internal_redirect
(which should die anyways) simply needs an apr_pool_join for the new pool.
Comments?
