            Bug ID: 58740
           Summary: incorrect access check of static base class member in
                    derived template class
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: lhyatt at gmail dot com

///////////////
class A {
    static int p;
};
int A::p = 0;
template<int=0>
struct B : A {
    B() {(void)p;}
};
int main() {
    B<>();
}
///////////////

This should fail to compile as A::p is private, but gcc accepts it.
