Question

我使用Qt Creator 4.0.3开发了一个小型Qt应用程序，基于Qt 5.7.0（MSVC 2013,32位）。它有一些GUI功能，2个UI表单，并执行一些计算。我在Windows 7 SP1（64位）上工作。

无论如何，它在调试模式下工作正常（从Qt Creator编译和执行）。在发布模式下编译也没问题，但是当我在发布模式下启动它时，应用程序从一开始就崩溃了，我收到以下错误消息：

Nom d'événementdeproblème：APPCRASH

我真的无法猜测问题是如何解决的，它阻止我跳到部署过程的下一步（顺便说一句，当双击时尝试直接执行应用程序时出现同样的错误它，甚至在使用windeployqt并添加所需的DLL之后......）。

这是我的.pro文件：

编辑：

查看JIT Visual Studio调试器窗口，我得到以下输出：

...基本上说有些模块（包括Qt5Widgets.dll）是“没有符号构建的”，但我不知道如何解释这个......

好的，我刚刚忘记在MainWindow的实例化中删除未初始化的QAction对象。将它添加到QMenuBar没有让应用程序在调试模式下崩溃，但是DID让它在发布模式下崩溃了！太棒了！

从QtCreator启动时，Qt应用程序无法在发布模式下启动（Qt5widgets.dll错误＃c0000005）
