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: unassigned@gcc.gnu.org
ReportedBy: jwcacces@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;

I don't think it's a bug.
G++ doesn't ignore access checking, you never use the name PVT so there's no
violation. The type exists, you just can't access the name PVT.
But you can give it a new name e.g.
template<typename T>
void f(T t)
{
typedef T type;
}
f(c.p());
Or, closer to the auto case:
decltype(c.p()) p = c.p();
