Bug ID: 58993
Summary: failure to access pointer to protected member method
in base from derived class specialization
Product: gcc
Version: 4.7.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: cvs at cs dot utoronto.ca
Sample code:
class base {
protected:
typedef void (base::*foo_type)() const;
void foo() const {}
};
template <typename T>
struct bar : public base {
foo_type test() {
return &base::foo; // OK
}
};
template <>
struct bar<void> : public base {
using base::foo;
foo_type test() {
foo(); // OK
base::foo(); // OK
foo_type x = &bar::foo; // OK
return &base::foo; // error
}
};
int main() {
bar<int>().test();
bar<void>().test();
return 0;
}
Compiler output:
protected_base.cpp: In member function ‘void (base::*
bar<void>::test())()const’:
protected_base.cpp:5:10: error: ‘void base::foo() const’ is protected
protected_base.cpp:22:23: error: within this context
