OOPS, didn't checked this list first.
Yes, AFAIU even control channel is unable to login to FTP.

BTW I have a server that once per day tries to download several files
from FTP via SOCKS4 proxy and strangely enough sometimes it's able to
download them! Probably it happens when connection from the previous
download attempt wasn't closed.

In my case this simple patch fixed the problem, but I'm pretty sure it
breaks something else :)
(here I removed call to Curl_connected_proxy() from multi_runsingle())
