私はバックグラウンドでデータを更新するスレッドがかなり複雑なQML/C++ハイブリッドアプリケーションを使用しています。QT終了時にQML/C++アプリケーションがクラッシュする
QDeclarativeAbstractBinding::~QDeclarativeAbstractBinding()
{
Q_ASSERT(m_prevBinding == 0); //<---- THIS GUY IS THE OFFENDING LINE
Q_ASSERT(m_mePtr == 0);
}
、ここでは、スタックトレースです：

質問： どうすればこの問題を解決できますか？私のコードで何が間違っているのでしょうか？これがどう起こるかに関する情報はありません。
ここであなたが何を求めているのか分かりません。アサーションが失敗した場合、それはその時点で 'm_prevBinding！= 0'を意味します。あなたの質問に文脈がないので、私はあなたがアドバイスを求めているかどうか本当に分かりません。 – Mat
