[cfe-dev] Build error for Release+Asserts with a clean repo from clang

[Manman Ren]

Thanks for the replies.

I got a clean repo for llvm+clang+… and created build directories for Debug and Release. For Release, I used "../llvm/configure --enable-optimized --with-externals=/Users/mren/llvm-mren/llvm/projects/external-tests/". 

I also did "make clean" and "make update"
make clean

Still got the same error :)

I figured it is probably related to my setup, since nobody else has complained.

Thanks,
