Some more info
At the moment I cannot update ESLint to version 5.*
To see the error on my project I run grunt eslint --stack --debug.
Is it possible the crash is because I do not use eslint-plugin-typescript and its typescript/no-unused-vars rule? Nonetheless I would expect an ESLint error and not a crash.
