That's of course not as cool. :-(

As you manage to complete the operation with other tools, it sounds as if
you've hit a bug.
What version of libcurl is this?

network sniff on what actually happens on TCP-level when it stops the
transfer, or what the send() (in Curl_write() in lib/sendf.c) returns etc.
