gcc(バージョン10以降)を使いAddressSanitizer(ASan)を有効にしてビルドすると書き込みのプレビューでトリップを表示するときにクラッシュすることがあります。
今のところ影響は開発者やメンテナーに限られているため直接修正はせずASanを有効にするときの注意と回避策をREADMEに追加して詳細はgithub issueのリンクに誘導します。
背景
リンカの
-Wl,--as-needed
フラグをつけて-fsanitize=address
でコンパイルするとlibcryptではなくlibasanの中にあるcrypt, crypt_rがリンクされますが実体がなく呼び出すとSIGSEGVが発生します。https://bugzilla.redhat.com/show_bug.cgi?id=1827338
