build.log

While updating the world set using emerge -uDNU @world, the compilation of sys-devel/clang-17.0.1 failed. The error log indicates multiple undefined symbols during the linking stage, such as llvm::Twine::str[abi:cxx11]() const, llvm::StringRef::upper[abi:cxx11]() const, and others.

Additional Context:
I am using an Clang profile.

I was encountering these same errors while building clang-17.0.2.

I've tried all machinations of changing CFLAGS and rebuilding dependencies, but I finally got it to build by running "emerge -ave --keep-going system". 

I'm not sure what dependency is the culprit, but it is not:
 sys-devel/llvm-common-17.0.2 
 sys-devel/llvm-17.0.2-r1 
 sys-devel/llvm-toolchain-symlinks-17 
 sys-devel/lld-17.0.2 
 sys-devel/lld-toolchain-symlinks-17 
 sys-devel/clang-common-17.0.2 
 sys-devel/clang-17.0.2 
 sys-libs/llvm-libunwind-17.0.2 
 sys-devel/clang-toolchain-symlinks-17 
 sys-libs/libcxxabi-17.0.2 
 sys-libs/compiler-rt-17.0.2
