This issue is caused by a [V8 engine upgrade](https://github.com/v8/v8/commit/79cdd69a1cfa9d3b4d9b6dec7203db4dabe618b4) that changes the behaviour of `Hoek.clone()`. A fix is proposed in: https://github.com/hapijs/hoek/pull/390

#### What are you trying to achieve or the steps to reproduce?

```js
const error = new Error("fail");
const boom = Boom.badImplementation(error);

assert.equal(boom.stack, error.stack);
```

#### What was the result you got?

```
