Since you're not using active FTP, enabling EPRT makes no difference.

Are you really using 7.10.6? Because we've recently made a change that should
make VERBOSE also show all incoming headers...

Since you doesn't seem to get to see any incoming headers when using VERBOSE,
you can instead set CURLOPT_DEBUGFUNCTION and output all incoming headers as
well it would help us debug/understand this! (The command line tool does this
when you use -v.)

The fact that it says "Connected the data stream" before returning an error is
a bug. I noticed that now because of your report here! ;-)

The 13 error is CURLE_FTP_WEIRD_PASV_REPLY which certainly indicates that the
server returned a response that libcurl couldn't parse. That's why I'm very
curious in getting to see that exact header line.

Set a break-point in the PASV parsing code and single-step from there!

Nope. It should deal with PASV when used like this.

That server probably returns a different response line.

That client has a different response parser. Obviously more functional in this
case. Does that command really use PASV?
