--- Comment #2 from Balakrishnan B <balakrishnan.erode at gmail dot com> ---
This has nothing to do with inheritance. If the inner class is template, access
specifiers are ignored. Simpler example:

class A {
    struct B1 {};

    template<class T>
    struct B2 {};
};

void foo() {    
    //A::B1 b1; //This doesn't compile (GOOD)
    A::B2<int> b2; // This compiles (BAD)
}

Bug is present in all versions between GCC 6.1 to trunk. GCC5 and earlier are
good.
