I just tried the example provided about using libuv with curl (http://curl.haxx.se/libcurl/c/multi-uv.html), and it does have the same issue.

On the add_download function, I've set the timeout to be low enough to create a timeout:

curl_easy_setopt(handle, CURLOPT_WRITEDATA, file);
curl_easy_setopt(handle, CURLOPT_URL, url);
+ curl_easy_setopt(handle, CURLOPT_CONNECTTIMEOUT, 2);
+ curl_easy_setopt(handle, CURLOPT_TIMEOUT, 2);

And it will fail with the same error I'm having.

Added download http://www.google.com:81 -> 1.download
* Rebuilt URL to: http://www.google.com:81/
* Hostname was NOT found in DNS cache
*   Trying 200.149.119.118...
* After 695ms connect time, move on!
* connect to 200.149.119.118 port 81 failed: Timed out
*   Trying 200.149.119.104...
Assertion failed: ((handle)->flags & UV__HANDLE_CLOSING) == 0, file ..\..\..\..\
deps\libuv\src\win\poll.c, line 190

I don't know for sure what is going on, mostly because I'm a noob, but from what I can understand, looks like libuv is trying to access the socket that was closed by libcurl on the trynextip function (https://github.com/bagder/curl/blob/master/lib/connect.c#L584).

And again, here the socket callback is called on the inverted order as on my example:

Added download http://www.google.com:81 -> 1.download
* Rebuilt URL to: http://www.google.com:81/
* Hostname was NOT found in DNS cache
*   Trying 200.149.119.108...

* After 937ms connect time, move on!
* connect to 200.149.119.108 port 81 failed: Timed out
*   Trying 200.149.119.84...

Assertion failed: ((handle)->flags & UV__HANDLE_CLOSING) == 0, file ..\..\..\..\
deps\libuv\src\win\poll.c, line 190

I will post this on libuv mailing list too.
