----------------------------------------
Bug #5803: closed output and Readline.readline dumps core
https://bugs.ruby-lang.org/issues/5803
Author: Nobuhiro IMAI
Status: Open
Priority: Normal
Assignee:
Category:
Target version:
ruby -v: ruby 2.0.0dev (2011-12-23 trunk 34110) [x86_64-linux]
=begin
libreadline 側の問題だと思うのですが、Readline.output= に指定した IO をクローズした後
Readline.readline で補完するとコアダンプしました。
"##\t" のところを色々変えてみるとコアダンプしたりしなかったりします。
$ cat readline_test.rb
require "readline"
IO.pipe do |r, w|
Readline.input = r
Readline.output = w
(w << "##\t").close
Readline.readline
end
$ ruby -v readline_test.rb
