A new kind of recurring failure that started in the last couple of day:

AM openssl !ipv6 !--libcurl:

FAIL 1265: 'NO_PROXY with IPv6 numerical address' HTTP, HTTP proxy, http_proxy, NO_PROXY, noproxy
FAIL 1324: 'HTTP with --resolve and [ipv6address]' HTTP, HTTP GET, --resolve
FAIL 2086: 'Pre-request callback for HTTP IPv6' HTTP, IPv6

https://github.com/curl/curl/actions/runs/14378524385/job/40318328714?pr=17012#step:41:3789

→ #17014

Also, a combination of gcc + xcode is broken again.
