OK, I think that I found how to reproduce the problem.
When the easy handle is removed from the multi while libcurl is still trying
to resolve the name of the proxy, it seems that the ftp struct is not yet
initialized at that time(?)... but the removal action calls Curl_done stuff,
hence the crash.

BTW, can I use a URL such as "http://armel:pwd@192.168.1.101:3128" as a
proxy specification (into CURLOPT_PROXY)? because my problems come when
'pwd' is missing (leaving "armel:@", it seems that libcurl then tryies to
resolve 'armel' as server and '@192...' as port or something like that)
would "socks://..." work as well? (or socks4 / socks5?)

Armel
