Steps to Reproduce

Regular build.

Anything else we should know?

clang-15

The build failure is in deps/json11/json11.cpp, with clang-15 identifying several unqualified move calls. Start by inspecting the reported constructors and fail path, then run a regular FreeBSD build; done means the build succeeds without the -Wunqualified-std-cast-call errors.
