@kzc this one reproduces on Node.js v18.8.0 but not on v16.17.0 − that whole v18 has been a complete mess (none of my reported issues have been fixed, and apparently it's now in LTS). I shall leave this as an exercise for the reader 😉 |

Is this a V8 or NodeJS issue? Can it be repro'd on latest Chrome? Have you ever tried uglify on https://bun.sh ? It uses the JavaScriptCore engine. |
