Bug #: 56248
Summary: [DR 580] access checking of template parameters done
too early
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Keywords: rejects-valid
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: redi@gcc.gnu.org
This code based on the example in [class.access]/6 is rejected:
class A {
typedef int I; // private member
template<int> struct Q;
template<int> friend struct R;
protected:
struct B { };
};
template<A::I> struct A::Q { };
template<A::I> struct R { };
struct D: A::B, A { };
t.cc:2:15: error: ‘typedef int A::I’ is private
typedef int I; // private member
^
t.cc:8:13: error: within this context
template<A::I> struct A::Q { };
^
t.cc:2:15: error: ‘typedef int A::I’ is private
typedef int I; // private member
^
t.cc:9:13: error: within this context
template<A::I> struct R { };
^
t.cc:6:10: error: ‘struct A::B’ is protected
struct B { };
^
t.cc:10:14: error: within this context
struct D: A::B, A { };
^
http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#580 clarifies that
access checking of the template parameters should be delayed until the context
is known.
