I have confirmed with eslint4b v7.20.0.
The following source code is the source code for at 25,907 line of the eslint4b/dist/core-rules.js file causing the infinite loop.
eslint4b/dist/core-rules.js
while (match = /\\[^\d]/gu.exec(value)) { validateString(node, match); }
In the original source code, the regular expression correctly uses one instance, so it doesn't go into an infinite loop.
https://github.com/eslint/eslint/blob/87c43a5d7ea2018cffd6d9b5c431ecb60caaf0d6/lib/rules/no-useless-escape.js#L210-L215
const pattern = /\\[^\d]/gu; let match; while ((match = pattern.exec(value))) { validateString(node, match); }
I think it's probably a build system bug, but I opened an issue here because I don't know which build system is wrong.
Maybe a bug in babel-plugin-minify-dead-code-elimination, but it doesn't seem to be fixed yet.
