            Bug ID: 42097
           Summary: variant:668:1: error: the parameter for this
                    explicitly-defaulted copy constructor is const, but a
                    member or base requires it to be non-const
           Product: libc++
           Version: 8.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal

See the simple example:

If you add const to the line 6, it magically works. So it does if you change
standard to C++2a
