[swift-dev] master fails to build

[Ben Ng]

I can’t seem to build master right now:

> git pull
> ./utils/update-checkout --clone-with-ssh
> ./utils/build-script --release --assertions
>
> (…)
>
> [17/558] Linking CXX shared library lib/swift/macosx/x86_64/libswiftCore.dylib
> FAILED: lib/swift/macosx/x86_64/libswiftCore.dylib
> Undefined symbols for architecture x86_64:

>       llvm::VerifyEnableABIBreakingChecks in Metadata.cpp.o

>       llvm::VerifyEnableABIBreakingChecks in Remangle.cpp.o
>       llvm::VerifyEnableABIBreakingChecks in SwiftNativeNSXXXBase.mm.o

Is anyone else running into this?
