I don't think you'd use the libc resolver at all when using DNS discovery, considering that it only runs once during startup of haproxy. Therefore I think it's unlikely that this would be a real world problem. Unrelated: the development branch of musl now has full DNS TCP support [1], so this will ultimately trickle down to Alpine at some point, resolving the issue once and for all.
