ruby -v: ruby 1.9.3dev (2010-05-08 trunk 27661) [x86_64-darwin10.3.0]

http_serverを読み込む設定のtermtterを起動しようとすると

[ERROR] SystemStackError: stack level too deep

になって起動後プロンプトもあらわれず停止します。^Cに応答しても異常終了に見えます。

問題が2つあって:

  1. (たぶん)http_serverプラグインで例外が発生する
  2. その例外の処理が無限呼び出しになる

このうち2について、上のログではException#backtraceの値が "/Users/sorah/git/ruby/termtter/lib/plugins/http_server.rb:24" というStringになっているのが奇怪です。その結果、NoMethodErrorになる、と。再定義されていなければ、RubyのコアでArrayに強制しているはずなのですが。

irb(main):001:0> e = Exception.new
=> #<Exception: Exception>
irb(main):002:0> e.set_backtrace("hoge")
=> ["hoge"]
irb(main):003:0> e.backtrace
=> ["hoge"]
