cv-qualifier bug

[rnickb]

The following code compiles fine with clang and g++ (-std=c++14) but fails with icc 2016:

#include <iostream>

template<class Derived>
struct ConstBase {
  template<bool T = true>
  int f() const {
    return 3;
  }
};

template<class Derived>
struct Base : ConstBase<Derived> {
  using ConstBase<Derived>::f;
  template<bool T = true>
  int f() {
    const Derived& derived = static_cast<const Derived&>(*this);
    return derived.f();
  }
};

struct A : Base<A> {
};

int main() {
  A a;
  std::cout << a.f() << "\n";
  return 0;
}

Thanks for your report. I submitted this to the development team and I will let you know when I have more information (reference ID DPD200371618).

This issue is fixed in compiler version 16.0.1 (XE 2016 Update 1):

$ icpc -V -std=c++14 test.cpp
