I am not able to repro this error either. I tried two versions of clang:
clang version 11.0.0 (Red Hat 11.0.0-0.2.rc2.module_el8.4.0+533+50191577)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /bin
clang version 12.0.0 (https://github.com/llvm/llvm-project.git
07f1e1f44c87d1ee84caf13d6e5aa64eb7e1b068)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/local/bin
Thanks,
