--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. A regression from GCC 10.4.0.

A C++14 testcase (removing the auto from the operator()):
```
struct Q {
  int n;
  constexpr const Q* operator()(int) const { return this; }
};

extern const Q q;

template<int>
constexpr const Q* p =3D q(0);
```=
