indeed it could happen to any different static and dynamic types, but here it's better to be more specific for clarity, I think. The check only aims to find bugprone polymorphic objects anyways. (`expr.add` in the standard specifically highlights polymorphic objects as well.) https://github.com/llvm/llvm-project/pull/91951 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
