clang: Option 'help-list' registered more than once!
I’m trying to use clazy  with clang/llvm 4.0.0.
“clazy —version” works but if I want to compile something I get this error.
: CommandLine Error: Option ‘help-list’ registered more than once!
fatal error: error in backend: inconsistency in registered CommandLine options
clang-4.0: error: clang frontend command failed with exit code 70 (use -v to see invocation)

clang-4.0: note: diagnostic msg: PLEASE submit a bug report to and include the crash backtrace, preprocessed source, and associated run script.
clang-4.0: note: diagnostic msg: Error generating preprocessed source(s).
I reported it to clazy maintainer. He thinks it is a problem of alpine’s clang packging.
