Crash on parsing webpack dependency (neo-async)

When parsing `webpack/node_modules/neo-async/async.js` (basically [this file](https://github.com/suguru03/neo-async/blob/master/lib/async.js)), I get the following:

```
panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xc0000005 code=0x0 addr=0x0 pc=0x7ff6d18a88fc]
