Subject: [ruby-dev:50273] [Ruby trunk Bug#13961] String#unpack の warning メッセージが SHARABLE_MIDDLE_SUBSTRING=1 を考慮していない
Date: Sun, 01 Oct 2017 15:01:11 +0000 (UTC) [thread overview]
Message-ID: <redmine.issue-13961.20171001150109.bfb290f7a0d3ee34@ruby-lang.org> (raw)
In-Reply-To: <redmine.issue-13961.20171001150109@ruby-lang.org>
Issue #13961 has been reported by tommy (Masahiro Tomita).
----------------------------------------
Bug #13961: String#unpack の warning メッセージが SHARABLE_MIDDLE_SUBSTRING=1 を考慮していない
https://bugs.ruby-lang.org/issues/13961
* Author: tommy (Masahiro Tomita)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.5.0dev (2017-10-01 trunk 60085) [x86_64-linux]
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
String#unpack で不正なディレクティブが指定された時のwarningメッセージが指定文字列ではなくNUL終端まで出力してしまいます。
```
% ruby -we '"hoge".unpack(("o"*100)[0,24])'
-e:1: warning: unknown unpack directive 'o' in 'oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo'
-e:1: warning: unknown unpack directive 'o' in 'oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo'
```
次のパッチで直ると思います。
```diff
diff --git a/pack.c b/pack.c
index 327c478af8..532e03cb14 100644
--- a/pack.c
