Ah, if Curl_wait_for_resolv() returns != CURLE_OK, 'conn' should never be
touched again. This is a problem with C-ares too (but I failed to trigger that
situation). Removing Curl_disconnect() at end of Curl_wait_for_resolv(), the
crash is gone. But that causes a memleak for unknown hosts:

IMHO the resolvers should never invalidate 'conn'. Is there a nicer way
to clean up?
