[swift-dev] ToT failing to build?

[David Zarzycki]

Anybody else seeing top-of-tree (af34e394e7) fail to build? I’m on macOS 17A358a with Xcode 9M214v (beta 6) and building like so:

./utils/build-script --build-subdir="$(dirname $PWD)/t" --llvm-targets-to-build X86 --skip-ios --skip-tvos --skip-watchos -r

The build crash is below. Any ideas?
