Rubinius has a different arity for Object#instance_variables than MatzRuby, which is what causes this.
It is fixable, but I am going to move the milestone to after the 1.0 preview.
Thanks for the report.

But you must choose between fix RbYAML and fix Rubinius Core. The example is extracted from RbYAML code and alot of other libs depend on YAML

Aah. In that case, this is indeed in 1.0 territory.
