Would it be possible for you to update to a newer version? I see both the OpenSUSE containers in Gitlab have newer versions of Clang. The reasoning for selecting such versions is in the commit message, I simply see no point in maintaining support for older Clang versions if there's no-one that actually runs such builds. Just listing them as supported for being able to output a binary that's never run tested is not helpful. Thanks, Roger.
