One possible explanation is following: If you run the gem with IronRuby 1.0 it runs in 1.8.6 compat mode. There may be a condition that checks for the RUBY_VERSION in the gem. On Ruby 1.1.2 the RUBY_VERSION is 1.9.2 and thus some other code path might be executed that depends on Hash#flatten. I don't think we regressed, it's just a missing feature. Feel free to implement it and send a pull request.

Is there a regression here maybe ? -- Thibaut
