Output of build command

Using Clang built from an earlier trunk checkout there is a segmentation fault
when building lib/IR/CMakeFiles/LLVMCore.dir/AutoUpgrade.cpp.o.

Output from build in attachment.

I configured using

    LLVM_ROOT=/home/arrow/tmp/clang/llvm
    PROJECTS_ROOT=$LLVM_ROOT/projects
    CC=clang CXX=clang++ \
    cmake \
        -DCMAKE_C_COMPILER=clang \
        -DCMAKE_CXX_COMPILER=clang++ \
        -DCMAKE_BUILD_TYPE=Release \
        -DLLVM_INSTALL_UTILS=YES \
        -DBUILD_SHARED_LIBS=YES \
        -DLLVM_ENABLE_FFI=YES \
        -DLLVM_ENABLE_CXX1Y=YES \
        -DLLVM_ENABLE_MODULES=YES \
        -DCLANG_ENABLE_STATIC_ANALYZER=YES \
        -DLLVM_ENABLE_LIBCXX=YES \
        -DLIBCXX_CXX_ABI=libcxxabi \
        -DLIBCXXABI_LIBCXX_PATH=$PROJECTS_ROOT/libcxx \
        -DLIBCXX_CXX_ABI_INCLUDE_PATHS=$PROJECTS_ROOT/libcxxabi/include \
        ../llvm

I build using

    cmake --build . --config Release

There are previous version of Clang, libcxx and libcxxabi installed.

`clang --version` reports

    clang version 4.0.0 (trunk 276574)
    Target: x86_64-unknown-linux-gnu
    Thread model: posix
    InstalledDir: /usr/local/bin

I'm on a fully update Ununtu 16.04 system.
