This is a new error as of clang 15. We don't see the problem on our buildbot workers because we don't use the newest version of Xcode on the macOS 13 builder.

If -Werror had not been used, it would just be a warning, not an error; it's recommended not to use -Werror in ports for reasons such as these (new compilers being stricter than older ones).

I don't see any attempt in the log to fetch our binaries, so perhaps you forced a build from source? If you allow our binaries to be used, you won't encounter this error.

That said, this is an actual bug in xmlsec, and I've reported it to them here: ​https://github.com/lsh123/xmlsec/issues/627
