Bug #: 52965 Summary: c++11 - subclass is private, but g++ ignores access modifier when using auto Classification: Unclassified Product: gcc Version: 4.6.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: jwcac...@yahoo.com /* Is this a bug, that g++ ignores the private access modifier when using "auto type deduction"? Compile with g++ -std=c++0x private_access.cpp vs g++ -std=c++0x private_access.cpp -DUSE_AUTO This seems similar to bug 52816 */ class C { private: class PVT { }; public: PVT p() { return PVT(); }; }; int main(int, char*[]) { C c; #ifdef USE_AUTO auto p = c.p(); // why does this work (in c++11) #else C::PVT p = c.p(); // but this reports that C::PVT is private? #endif return 0; };
