The method insert_member_decl is declared virtual and defined in each of these. Unfortunately, it has different argument types in the base scope_decl class. Most calls to insert_member_decl are at a statically known class, but in insert_decl_into_scope the method is called via a scope_decl pointer. There is the possibility that this could be a type derived from scope_decl rather than scope_decl itself, in which case the base method would be called, not as intended. This commit adjusts the type of the member argument to scope_decl::insert_member_decl to match the other two classes and eliminates the last trigger of Clang's -Werror-overloaded-virtual. * include/abg-ir.h (scope_decl::insert_member_decl): Change type of member argument from const decl_base_sptr& to plain decl_base_sptr. * src/abg-ir.cc (scope_decl::insert_member_decl): Likewise.
