Subject: [ruby-dev:15430] [BUG] Segmentation fault/ruby 1.7.2 (2001-12-10)

渡辺哲也です。

今朝 12/13 (9 時くらい)の 1.7.2 の CVS で core する
ようです。

再現スクリプト書けなくて、コードを中途半端なまま引用
します。すいません。

c2html.rb:240: [BUG] Segmentation fault
------------------------------
class CMAIL < DelegateClass(Array)
  def initialize(file)
    @succ = nil
    file = File.expand_path(file)

    f = File.open(file)
    foo = NKF.nkf('-eZm', f.read)
    f.close

    @cmail_body = foo.split("\C-_\C-l")          # ^_^L
    @cmail_head = @cmail_body.shift.split("\n")
    @cmail_body.pop                                   # -- ここが 240

    @cmail_body.collect! do |mail|
      $dir = mail.to_time.strftime('%Y/%m/%d/%H%M%S')          # ////
      'Size: ' + sprintf("%d\n", mail.size) + mail.mail2str.join("\n")
    end
    super(@cmail_body)
  end
end

バックトレースです。
