Bug #4159: test_block_variables(TestRipper::ParserEvents) が失敗する
http://redmine.ruby-lang.org/issues/show/4159

起票者: Kouhei Y.
ステータス: Open, 優先度: Normal
ruby -v: ruby 1.9.3dev (2010-12-14 trunk 30209) [x86_64-linux]

test_block_variables(TestRipper::ParserEvents) が失敗することがあります。
どうも環境依存らしく、CentOS 5.5のマシンでは再現しますが、Debian lennyのマシンでは再現しません。

エラーメッセージからポイントされている [ruby-dev:39423] は以下のようです
