Sorry it has taken me a while to get back on this. Thanks for looking at it!

Curl_connect() could return CURLE_OK (0) fine if the resolving of the host was
only started and not finished (if 'async' was set TRUE), and then it should be
resolved asynchronously.

With a "plain" windows build, that resolving would be done using the threaded
resolve approach in hostthre.c

However, since test 504 is using a plain IP address, there's no "resolving"
done and Curl_connect() should return CURLE_OK (0) immediately with 'async'
set FALSE! It should then proceed to the CURLM_STATE_WAITCONNECT state
instead, and there it should probably fail rather soon.

Does this help you continue tracking this?
