IIRC there the default was none (implicit =delete) but some of the operators from AnyP::CfgPort try to make use of it. I dont recall which system or compiler version specifically sorry. But CfgPort should only have copy-construct actions done on it for split-stack OS such as OpenBSD. So maybe it only shows up there. IIRC it was originally found in the BuildFarm testing so if this patch passes the current BuildFarm matrix it can go in. And/or just apply and add a proper ctor later if needed. (I'll tentatively +1 this as-is if you want to do the latter).
