が、ここからどのようにして問題を絞り込んでいけば良いのか悩んでいます。 ---------------------------------------- Bug #13746: windows-pr gemのRuby　2.4 32bit版でのSEGV https://bugs.ruby-lang.org/issues/13746#change-65857 * Author: cosmo0920 (Hiroshi Hatake) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: ruby 2.4.1p111 (2017-03-22 revision 58053) [i386-mingw32] * Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN ---------------------------------------- windows-pr gemのCI対象にRuby 2.4 32/64bit版の両方を加えてAppVeyorにてCIを走らせたところ、SEGVが発生しました。 このSEGVはRuby 2.4の64bit版（ruby 2.4.1p111 (2017-03-22 revision 58053) [x64-mingw32]）では発生しません。 windows-prのリポジトリは https://github.com/cosmo0920/windows-pr です。 git clone後、bundle install && bundle exec rake test:allでテストが走るようになっています。 SEGVの内容は以下の通りです。 ```
