So it works with the command line tool but not with libcurl? Are you 100% sure
they are using the same libcurl? Is there any chance your libcurl test runs
with libcurl without TLS support? (Your code doesn't show you checking the
curl_easy_setopt() return values.)

Otherwise I suggest setting a break-point at lib/ftp.c:2651 and single-step a
few steps from there to figure out what's wrong!
