Since r64852, on Solaris with Oracle Developer Studio 12.6, compile error of iseq.c

Added by ngoto (Naohisa Goto) over 5 years ago. Updated over 5 years ago.

Status:
Third Party's Issue
Target version:
-
[ruby-dev:50665]

Description

r64852以降、Solaris 10 上の Oracle Developer Studio 12.6 にてコンパイルすると、以下のエラーでiseq.c のコンパイルに失敗します。(r65641 にて確認)

flag という変数が再定義された、というエラーが出ていますが、理由はよくわかりません。
当該コンパイラ Oracle Developer Studio 12.6 のバグかもしれないと疑っています。
なお、前バージョン Oracle Developer Studio 12.5 では発生せず正常にコンパイル終了します。
(Oracle Solaris Studio 12.4 以前ではさらに別のエラーが発生しますが、別チケットにて報告します。)

以下のように、Cのマクロの定石の一つである do-while(0) でブロックを囲むコードに変更すると、エラー無くコンパイルできるようになりました。

iseq.c のコンパイルは通りましたが、謎のリンクエラーが発生していました。
コンパイラまたは周辺のバグかもしれませんが全く不明です。

さすがにこれはOracle Developer Studio 12.6のバグっぽいので、まだBetaなようですしコンパイラ側に報告してもらえませんか。

Updated by ngoto (Naohisa Goto) over 5 years ago

実は既に2017年7月頃に正式リリース済です。
https://www.oracle.com/technetwork/server-storage/developerstudio/downloads/index.html
日本語翻訳のページはベータ時のまま放置されているため、誤解されても仕方ないとは思います。

Oracleに報告しようと試みましたが、窓口が不明のため中断しています。

私が実用上不便に感じたらWorkaroudを入れるかもしれません。
