Bug #3782: NendoのテストスイートでSEGVが発生する

=begin
私の個人的なプロジェクト(Nendo)のテストスイートを実行するとSegmentation FaultでRubyが落ちます。
RSpecで定義したテストスイートをなるべく短かくする努力はしてみたのですが、これが限界のようですので、あきらめて私の作ったミニマムのものを残した上で現象の報告をします。

※ テストスイートが短かくなったとはいえ、NendoはLisp処理系でありRubyのevalを多様していますのでバグの解析の難易度は高そうです。

今後、いつでも現象を再現させられるように、github上のNendoリポジトリにブランチ(ruby192_segv_environment) を作成しておきました。
以下、再現手順です。

=begin
同じSnow Leopardの1.9.2で試したが再現しません。
rvmを使っているような気がするんですが、使わないようにしたら正しく動きませんか。
=end

[kiyoka (Kiyoka Nishiyama)]

=begin
rvmは使っていません。
GNU stowというツールを使って、/usr/local/stow以下にインストールしたものを、/usr/local以下にシンボリックリンクしています。(GNU stowの機能)
また、再現性は100%ではありません。
私の環境でも、時々SEGVせずに通ることもありますが、何度も実行しているとSEGVする回数のほうが多いという状況です。

=end

[naruse (Yui NARUSE)]

=begin
stowとかを用いずに/home/foo/hogeとかにインストールするとか、
1.9.2ブランチ先端とかでも再現しますかね。
