Additional Info
At the moment I cannot update ESLint to version 5.*
See also eslint/typescript-eslint-parser#553
See quadre-code/quadre#103 where I upgraded typescript-eslint-parser, when I got this error.
Trying to use this plugin didn't fix the crash.
To see the error on my project I run grunt eslint --stack --debug.
