Almost everything has been failing at least once on freebsd-15, e.g.: - https://github.com/rust-lang/libc/pull/3966/checks?check_run_id=31530590009 - https://github.com/rust-lang/libc/pull/3963/checks?check_run_id=31497998977 - https://github.com/rust-lang/libc/pull/3960/checks?check_run_id=31394381764 I don't know why this would be, considering freebsd-13 and freebsd-14 seem to work fine.
