@tilo With the current Ruby 3.2.0dev ruby/ruby@56cc3e9, it looks like no error according to the latest build.

Can you try the latest Ruby 3.2 head to reproduce?

I was running into the same error and tried to reproduce it. In the end I just saw the error with rake 11, but was unable to repro with the current rake. I assume you'll be able to fix the problem by bumping rake to the most current version which appears to support ruby 3.2 just fine.

This was fixed by #297.
