The lit test in lit/Modules/lc_build_version.yaml fails on Darwin systems,
crashing here -

Where the loadPDBFile line 73 is
59 static std::unique_ptr<PDBFile> loadPDBFile(std::string PdbPath,
60 llvm::BumpPtrAllocator
&Allocator) {
61 llvm::ErrorOr<std::unique_ptr<llvm::MemoryBuffer>> ErrorOrBuffer =
62 llvm::MemoryBuffer::getFile(PdbPath, /*FileSize=*/-1,
63 /*RequiresNullTerminator=*/false);
64 if (!ErrorOrBuffer)
65 return nullptr;
66 std::unique_ptr<llvm::MemoryBuffer> Buffer =
std::move(*ErrorOrBuffer);
67
68 llvm::StringRef Path = Buffer->getBufferIdentifier();
69 auto Stream = llvm::make_unique<llvm::MemoryBufferByteStream>(
70 std::move(Buffer), llvm::support::little);
71
72 auto File = llvm::make_unique<PDBFile>(Path, std::move(Stream),
Allocator);
73 if (auto EC = File->parseFileHeaders())
74 return nullptr;
75 if (auto EC = File->parseStreamData())
I'm not sure why this wouldn't fail on a linux/windows system. The point of
the .yaml lit tests was that it is host independent?
