Comment

If this isn't a bug in using typescript, it might be a bug in typescript itself, but I've only encountered it while using this rollup plugin. Please feel free to pass the buck to the TS team if
appropriate;-)

workaround/possible fix: in typescript.js, line 80338, protect property.name.kind by checking for property.name first.

@clausreinke after running your repro it looks to me like the problem exists with typescript. I'm not a TS expert so I can't provide guidance there, but the stack trace is solely within the typescript module itself.
