--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Hmm:
  D.2948._startTime.D.2792 = 0;

That seems wrong.

Reduced further:
```
struct SimpleRefCounted {
  virtual void addRef();
};
struct ClockImpl : SimpleRefCounted {
  long tv_nsec;
  int : 0;
};
void f() { ClockImpl b{}; }
```
And yes it is the zero sized bitfield causing issues ...
