I assume this libcurl is not built to use c-ares for name resolves? If so, I
simply cannot see anything that would point to this being libcurl's fault, but
instead rather a problem in the resolver lib/function of your operating
system. libcurl itself makes no DNS packets at all, it just calls defined APIs
of underlying libs.

Can you repeat this problem on any other operating system or libcurl built to
use c-ares?
