 > This part compiles fine now for me, but now v1.2.0 seems to have another
 issue in src/ui/dialog/objects.cpp where it doesn't compile a call to
 extract() although gnu++17 is switched on, but that's for another ticket.

 Confirmed, I'm also seeing these issues on 10.13. Building with a newer
 version of Clang solves both, and I'll push a fix momentarily.
