Details: macOS Sequoia 15.0.1 cmake 3.30.5 ninja 1.12.1 llvm commit SHA 8445a95309f2e8673c967f78739e18f32f5208bf

Any thoughts on the cause of this error? (If not, can you provide the tooling version numbers and llvm-mos commit sha for the last successful Mac build? I can try to repro with that information on my end.)
