I'm not 100% sure of the error because there's not much of a stacktrace. But quite simple tests which pass in all other rubies fail in Truffleruby for some reason.

In TruffleRuby head (2 months ago)

truffleruby 25.0.0-dev-d3120a20, like ruby 3.3.7, GraalVM CE Native [x86_64-linux]

These tests passed

In TruffleRuby today

truffleruby 25.0.0-dev-a65bde3d, like ruby 3.3.7, GraalVM CE Native [x86_64-linux]

These tests fail.

Tests in question are 3 that use the follow snippet style: allow(registry.current_world).to receive(:target) { target }

Any advice / next steps greatly appreciated
