Bug #14085: many redefinition warnings on test/win32ole/test_word.rb

• Status: Closed
• Priority: Normal
• Assignee: suke (Masaki Suketa)
• Target version: -
• ruby -v: ruby 2.5.0dev (2017-11-06 trunk 60666) [x64-mswin64_100]
• Backport: 2.3: UNKNOWN, 2.4: UNKNOWN

win32oleのテストで、以下のような警告が出ます。
警告が出るのは WIN32OLE.const_load(w, Word) というコードですが、
該当コードが複数回呼ばれているわけではなくて、これを1回呼ぶだけで、
定数の再定義が何度も行われてしまうようです。
実害はないような気もしますが、できれば出ないようにできないでしょうか？

#13984 で入れたんですけど、一旦、戻しましょうか。

WIN32OLEから定数を取得するときに、Wordサーバから複数回、同じ定数を返されるので、そうなるんですよね。
warningの対策は別で考えるとして。

[usa (Usaku NAKAMURA)]

実害ないのなら、revertまではしなくていいんじゃないかと思います。
2.5.0のリリースまでに対策するということで。
