--- Comment #5 from Patrick Palka <ppalka at gcc dot gnu.org> ---
Reduced version of the original testcase:

struct integral_constant {
  constexpr operator int() const { return 42; }
};

template<int N>
struct A {
  static constexpr int value = N;
};

template<class T>
struct B {
  static constexpr int value = T::value;
};

template<class T>
void f(T t) {
  using alias = A<t>;
  [](auto) {
    B<alias> a; // { dg-bogus "'t' is not captured" }
    return a.value;
  }(0);
}

template void f(integral_constant);
