acorn-lose error with tern 0.23.3 or up

[oeddyo]

Hi @marijnh

First of all thanks for this amazing software (and many other things like CM)!

I just found that if you use tern with version 0.23.3 and up in react project, it will report an error as below. If I downgrade tern to 0.22 then it's all fine. Could you take a look and see if it's a bug please?

Thanks
