no-unused-prop-types crash when destructuring prevState

[daltones]

If I use destructuring on the second argument of componentDidUpdate, like this:

import React from 'react';

export default class Test extends React.Component {
  componentDidUpdate(prevProps, {state1, state2}) {
  }
}

It gets this error:

Error: Cannot read property 'length' of undefined

Also having this problem.

It fails on this destructuring:

constructor(props, { store }) {
    super(props);
}
