We'd like to keep other warnings that -Weffc++ generates: it worked nicely for us until this point. > There are lots of known issues with -Weffc++ and noone has been motivated to > fix them, see e.g. PR 22395 comment 5 and PR 16166 comment 3 for some > discussion related to this warning. Too bad. This one could probably be a one-liner to just disable this warning since -Wnon-virtual-dtor is already enabled with -Weffc++ (and it does a better job). But "noone has been motivated" says it all. Anyway, thanks for the pointers.
