突然 (どうやら) Bootstrap (LESS) ソリューションを使用した完全に機能する MVC5 が実行を拒否しました。実行しようとすると、空白の画面が表示され、サイトが読み込まれません。
デバッグ モードで実行すると、約 90 秒後に次の例外でクラッシュします。
Exception thrown: 'System.AccessViolationException' in ClearScriptV8-32.dll
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
ただし、を削除すると、ソリューションは正常に実行されます/bootstrap/less/grid.less。
私が試したこと
V8エンジンをMsieに交換してみました。これはまた、それが問題であることを示唆してgrid.lessいます。特に、次の行を指しています。.make-grid(sm);
どこかで示唆されているのを見て、AVをオフにしてみました。違いはありませんでした。
私はそれをグーグルで検索しましたが、明らかに関連する唯一の情報はこのリンクでした。ReactConfig.csプーリングをオフにすることを提案していますが、ファイルがないため、これを行う方法がわかりません。または、それが私のソリューションに関連するかどうかもわかりません。
https://github.com/reactjs/React.NET/issues/102
私は私の深さから少し外れています。この問題を調査/デバッグする方法を誰かが助けたり提案したりできますか?
ありがとう！！
問題が見つかりました。ブートストラップ LESS ファイルが 2 回含まれていました。以下に答えてください。
