Qt 라이브러리 또는 내 응용 프로그램의 버그입니까?

Qt 라이브러리 (4.7 및 4.7.1에이 문제가 있음)를 사용하여 앱을 작성했으며이 앱은 주로 웹킷 (웹 페이지 표시) 및 Qt-webkit 브리징 (C++ 클래스를 Javascript 객체에 매핑)을 처리합니다. 그러나 다음 세그 폴트가 있습니다.Qt 라이브러리 또는 내 응용 프로그램의 버그입니까?

소스의 예가 있으면 도움이됩니다. 그렇지 않으면 문제를 해결하기가 어려울 수 있습니다. –

자신 만의 소스 코드로 최소한의 예제를 제공하지 않는다면 지금 말할 수 있습니다. – BastiBen

자신의 앱. (그냥 추측 해.) – aib

경고 : "소스 파일이 실행 파일보다 최신입니다." 이상하다. Qt 소스를 컴파일 했습니까? 또는 최신 버전의 소스 및 헤더와 이전 버전의 라이브러리를 사용합니까?
