    Shortest reproducible example and environment: https://godbolt.org/z/Ys3fnjzKn

Reproduced here for posterity:

```c++
struct Base {
    // Needs at least 3 fields
    double a = 0.;
    double b = 0.;
    double c = 0.;
 // Works with constexpr
    static consteval Base zero() {
 return Base{0., 0., 0.};
    }
};

struct Derived: public Base {
    static consteval Derived zero() {
        return {Base::zero()};
    }
};

/*
// Works
Base get_base() {
 return Base::zero();
}
*/

// Crashes
Derived get() {
 return Derived::zero();
}
```
