--- Comment #4 from pipcet at gmail dot com ---
I believe this invalid code triggers the same bug, and might be easier to
analyze:

extern int fn();

template<class F>
class X {
public:
  template<F f> class Y {};
  template<F f> void y() {}
  X(F f)
  {
    Y<f> y;

    y.value();
  }
};

int main() { const X<decltype(&fn)> x(fn); }



In both cases, an identifier is used twice ("y" here, "ptr" in the original
example), and renaming one instance to avoid the name clash avoids the ICE.
