[cfe-users] compile error

[Mani]

Hi all,

i have been compiling clang for months without problems, until about last week. Since then I can't compile.

usually delete CMakeCache.txt then run
cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_C_COMPILER=/usr/local/bin/clang -DCMAKE_CXX_COMPILER=/usr/local/bin/clang++ -DCMAKE_CXX_FLAGS="-std=c++11 -stdlib=libc++" -DCMAKE_SHARED_LINKER_FLAGS="-std=c++11 -stdlib=libc++" -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_WERROR=OFF -DLLVM_BUILD_TOOLS=ON -DLLVM_BUILD_EXAMPLES=OFF -DCLANG_BUILD_EXAMPLES=OFF -DLLVM_APPEND_VC_REV=ON /Users/Mani/Development/Projects/llvm/source
ln -s $PWD/compile_commands.json /Users/Mani/Development/Projects/llvm/source

and then run 
make -j10 ENABLE_OPTIMIZED=1 DISABLE_ASSERTIONS=1

Here is what i get.

Anybody know what going on?
