Does covered support TruffleRuby?

[mtortonesi]

Looking at .github/workflows/test.yaml it looks that "covered" supports TruffleRuby - or at least aims to. However, when trying it with TruffleRuby 23.0.0 I get the following error:

/Users/mauro/.rbenv/versions/truffleruby+graalvm-23.0.0/graalvm/Contents/Home/languages/ruby/lib/truffle/coverage.rb:11:in `start': wrong number of arguments (given 1, expected 0) (ArgumentError)
	from /Users/mauro/.rbenv/versions/truffleruby+graalvm-23.0.0/graalvm/Contents/Home/languages/ruby/lib/gems/gems/covered-0.21.0/lib/covered/capture.rb:15:in `start'

Is this a known bug or just some configuration mistake on my side?

Should I file an issue?

Honestly, this is the root cause/fix: truffleruby/truffleruby#3150

We can work around it in this gem, but I feel like it would just be better to fix it in TruffleRuby.

I totally agree. This should be fixed upstream. That's why I opened a discussion instead of submitting an issue in the first place.
