Issue #8644 has been updated by akr (Akira Tanaka).
File test_closed_outstream-segv.txt added
readline のテストについて報告したのですが、
内容が長すぎたのか、途切れてしまったので、
SEGV したときのログを添付します。
あと、長すぎたためか、メールも ruby-dev には流れなかったようです。

Bug #8644: valgrind error in a readline test
https://bugs.ruby-lang.org/issues/8644#change-40532

ruby -v: ruby 2.1.0dev (2013-07-16 trunk 42006) [x86_64-linux]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN
test-all が readline のところで SEGV することがあったので、
とりあえず valgrind をかけてみたところ、ひとつ問題を指摘されました。

ちょっとソースを見たところ、fclose した後に fileno しているようですが、
これはよろしくないんじゃないでしょうか。
valgrind で指摘されたのが原因かどうかはわかりませんが、
SEGV したときのログもつけておきます。

問題は、readline_s_set_input や readline_s_set_output で、
IO オブジェクトから rb_io_stdio_file で FILE * を入手し、
rl_instream や rl_outstream へ代入していることにあります。
IO#close では rl_instream や rl_outstream に残っていることは気にせず、
FILE * を fclose し、ファイル構造体は開放されるので、
その後で (readline_readline で) fileno(rl_instream) や fileno(rl_outstream) をすると
Invalid read になります。
もし、ファイル構造体のあったメモリが OS に返却されていれば SEGV になってもおかしくないでしょう。
rb_io_stdio_file で入手した FILE * はいつ消えてもおかしくないので、
rl_instream や rl_outstream へ代入してとっておくのはよろしくないのではないでしょうか。
ファイル構造体をどうしてもとっておく必要があるなら、おそらく、fd を dup して fdopen で
ファイル構造体を新しく作って代入するような方向性がいいんじゃないでしょうか。
もちろん、そうやって dup/fdopen で資源 (新しい fd, ファイル構造体) を確保するなら
開放する手立ても必要でしょう。
readline_readline で errno == EBADF で検査する代わりにもともとの IO オブジェクトが
クローズされているかどうかを調べてクローズされていたら開放するとか、
readline_s_set_input や readline_s_set_output で nil を受け付けるとか、
いくつか考えないといけないとは思います。

To: ruby developers list
Issue #8644 has been updated by akr (Akira Tanaka).
File readline-fix-invalid-read.patch added
とりあえず、close されたかどうかは元々の IO オブジェクトが
close されたかどうかで判断するようなパッチを書いてみたんですが、
どうですかね。
なお、やってみて気がついたのですが、
isatty して EBADF になることを確認するというコードがあって、
しかも Readline.readline のドキュメントにその挙動が
* Raises IOError exception if below conditions are satisfied.
* 1. stdin is not tty.
* 2. stdin was closed. (errno is EBADF after called isatty(2).)
と明記されているのですが、
そもそも EBADF を検査するのは間違っている (常に他のスレッドや
signal handler が fd を open する可能性はあるので確実でない) というのと、
実際に isatty で tty でないときに IOError にしてみたら、
テストが失敗しまくる (テストではパイプを stdin に設定している)
というわけで、ここは isatty は気にしないように変えてみました。
