Issue #15292 has been updated by ngoto (Naohisa Goto).
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。

Issue #15292 has been updated by naruse (Yui NARUSE).
Status changed from Open to Third Party's Issue
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。

Issue #15292 has been updated by ngoto (Naohisa Goto).
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。
