TypeError: Cannot read property 'type' of null in jsx-no-bind rule

The following file seems to cause the jsx-no-bind rule to crash:

let foo;

He's a full set of reproduction steps. See the attached package.json and yarn.lock files for specific versions (2017-11-18_eslint-bug-jluxenberg.zip):

This is already reported ( #1543 ) and a fix has been merged ( #1544 ).

Hopefully a v7.5.1 will go out later today!

Thanks for understanding 👍

Hah! Just tried to reproduce on master and couldn't (was going to open a PR). Thanks for your response!
