--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The check against 1 comes from:
```
template <typename Type>
inline bool
pointer_hash <Type>::is_deleted (Type *e)
{
return e == reinterpret_cast<Type *> (1);
}
```
So there is no check that the entry has been deleted ...
But I don't see how deleted could show up here.
