Subject: [ruby-dev:42963] [Ruby 1.9-Bug#4238][Open] GC.stress 下で OptionParser で設定のない引数をパースさせると core

Bug #4238: GC.stress 下で OptionParser で設定のない引数をパースさせると core
http://redmine.ruby-lang.org/issues/show/4238

起票者: Makoto Kishimoto
ステータス: Open, 優先度: Low
カテゴリ: core
ruby -v: ruby 1.9.3dev (2011-01-06 trunk 30471) [x86_64-freebsd8.2]

r29832 以降で起きます

以下のようなスクリプトを実行すると、

$ cat optparse-core.rb
require "optparse"

parser = OptionParser.new
GC.stress
parser.parse! ['-a']

以下のように core を吐きます。

$ ruby19 optparse-core.rb
/usr/local/lib/ruby/1.9.1/optparse.rb:233: [BUG] Segmentation fault
