Hi, I removed the check for !numfds and now it works perfectly for both versions, with c-ares and the threaded resolver. Calling curl_multi_perform if numfds is 0 seems not to be a problem. Anyway, c-ares is a little bit faster in my case, so I'll stick with that.
Thank you very much for your assistance!
