Product: gcc Version: 4.9.1 Status: UNCONFIRMED Severity: minor Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: rohan at rohanlean dot de Created attachment 33384 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33384&action=edit small testcase Suppose that three classes are related by inheritance (B ---> A : B inherits from A) as follows: C ---private--> B ---public--> A Then C can publish A via using B::A; I think that the correct behaviour is to reject such a program. ^ permalink raw reply [flat|nested] 3+ messages in thread
