--- Comment #1 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Daniel Fruzynski from comment #0) > clang includes -Woverloaded-virtual in -Wall. Please do same for gcc. I was looking for a testcase to check and tried g++.dg/warn/pr61945.C but clang doesn't warn on that with -Wall. Do you have a better testcase to show how clang warns but gcc doesn't?
