Bug Report

Current Behavior
Cannot read property 'name' of null error is coming when babel is parsing.
Since target.node.id is null

Input Code

• Error code - http://bit.ly/2k7mzXL
• Working code - http://bit.ly/2lZu8QG
• Working code - http://bit.ly/2kzBt9e

This code breaks on repl with only es2015 preset selected

const E_ARR = [];

export default function () {
  const someVar = E_ARR;
  return [...someVar];
}

Expected behavior/code
This code is working though

export default function () {
  const E_ARR = [];
  const someVar = E_ARR;
  return [...someVar];
}

const E_ARR = [];

export default function namedFunction() {
  const someVar = E_ARR;
  return [...someVar];
}

Environment

• Babel version(s): https://babeljs.io/repl
• Node/npm version: https://babeljs.io/repl
• OS: [e.g. OSX 10.13.4, Windows 10]: OSX
• Monorepo: [e.g. yes/no/Lerna]: N/A
• How you are using Babel: [e.g. cli, register, loader]: https://babeljs.io/repl

Possible Solution
We believe it's being caused by the latest release this weekend.

Additional context/Screenshots
This same code was working before this weekend's release
