To me, this sounds like if the server hasn't actually flushed the file to disk
properly when you start to download it... but that doesn't explain why SIZE
would say the right value.

Then the server is broken or behind a firewall that doesn't track ftp sessions
or similar.

libcurl only changes to PASV is EPSV doesn't work, as in returns a response
code indicating that. In your case it seems to respond OK but then just not
act correctly.

Possibly a broken server implementation, possibly a firewall that tracks PASV
connections but not EPSV connections. Possibly something completely different.

I'd say you should contact the server admin and ask.
