Try CURLOPT_DEBUGFUNCTION to get to see exactly what it sent/received at the
point it stops.

And you forgot to mention what libcurl version on what platform you're using.

It may look funny to a casual reader, and I'd be surprised if the server
really has a path named '/\r\n\r\n', but libcurl doesn't mind much.

I don't think that header is the reason for the problems you experience.
