内容
Rust 1.79に上げるとC APIのテストがSEGV(多分)することがわかりました。
https://github.com/VOICEVOX/voicevox_core/actions/runs/9505427859?pr=799
原因は
voicevox_user_dict_add_wordの実装です。起こっていることはおそらくこんな感じです。https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=3d7d63d7dd6216fbb5172391013be984
voicevox_user_dict_add_wordは現在output_wordに書き込む方法を誤っており、16バイトではなく16×16=256バイトをmemmoveしてスタックを破壊しています。書き込む方法を正しくすることで修正を行います。関連 Issue
