32位Qt应用程序在Windows 7 x64上随机崩溃

32 bit Qt app crashes randomly on Windows 7 x64

本文关键字：x64 随机 崩溃 Windows Qt 应用程序 32位      更新时间：2023-10-16

我们有一个旧的代码库，我们在Windows XP SP3下使用c++ Qt框架(v4.6.3)开发。使用该代码库构建的应用程序在Windows XP下可以正常运行。

应客户要求，我们将应用程序部署到Windows 7 x64机器上。在那之后，当我们尝试启动应用时，我们在发行版本中遇到了随机崩溃问题。当它崩溃时，应用消耗了近2GB的内存。如果我们将应用程序兼容性更改为Windows XP SP3，崩溃问题就会消失。在调试模式下也不会发生崩溃。

我们收集了一些关于崩溃问题的日志。下面给出了日志:

导致崩溃的原因是什么?有什么想法或建议吗?

这仅仅意味着您的程序中存在错误。没有看到代码，很难知道在哪里。我建议使用cout或printf或qDebug()来检测代码运行良好的最后一行。这将给出发生错误的区域。这就是我如何解决我的错误在多线程程序。我还建议你看看这个
