Reduced to the test case below, and I can't see a way to fix this at present, anyone any bright ideas?
In case the problem is not clear to anyone... [extra declarations/definitions removed to focus on virtual inheritance]
class base { public: virtual void method1() = 0; };
class derived1 : virtual public base { };
class derived2 : virtual public base { };
class intermediate : public derived1, public derived2 { public: intermediate(int i) : base(i) {}
void method1(); };
class final : public intermediate { public: final(int i) : base(i) {} };
Both intermediate and final have a unique override of method1().
struct X : final, virtual intermediate { };
X has two intermediate subobjects, so there's no unique override of method1(). The question, then, is how to change is_virtual_base_of to account for this situation. That will require more thought. _____ Rob Stewart robert.stewart@sig.com Software Engineer, Core Software using std::disclaimer; Susquehanna International Group, LLP http://www.sig.com IMPORTANT: The information contained in this email and/or its attachments is confidential.
