Hi Mr. Kuleshov, Thank you for your bug report. I think that your report can be verified as a minor bug in compiling. However, we would be grateful if you would add info on the exact version of your clang, exact compilation options and your OS version. Thanks in advance.

This seems to have been fixed in 8.0.20 as a side effect of another change.
