我目前正在使用一个应用程序，试图将 BreakPad 集成到 Qt 应用程序中。我发现一个页面帮助我解决了很多初始设置和问题。
https://github.com/JPNaude/dev_notes/wiki/Using-Google-Breakpad-with-Qt
我仍然无法让它在实际异常情况下工作。我创建了一个演示应用程序，它也有同样的问题。以下是我要进行测试的步骤。我现在正在调试中进行测试。
这给我留下了一个 out.txt 文件。
当我在执行此代码的演示应用程序中调用 dumpFunc 时
Breakpad::CrashHandler::instance()->writeMinidump();
我得到以下输出

这很好，也是我想要的。但是当我实际上用 badFunc() 引发异常时。
int *myNull = NULL;
*myNull = 42;
我得到以下输出

这不是发生异常的实际堆栈跟踪。关于出了什么问题或者如何更改它以获得实际堆栈有什么想法吗？

我最近也掉进了同一个兔子洞。我从许多地方获取资源，将我发现的所有内容放在一起在此存储库中。
可能影响堆栈输出的因素之一是您用于编译应用程序的“优化级别”。如果强制创建调试符号也没关系。如果您应用任何优化，堆栈有时会显示不正确，因此您可以尝试在发布版本的 Qt 项目（*.pro 文件）中禁用优化，如下所示：
CONFIG *= force_debug_info
QMAKE_CXXFLAGS_RELEASE_WITH_DEBUGINFO -= -O2
我设法通过更新非常旧版本的 dump_syms.exe、minidump_stackwalk.exe 并将 msdia140.dll 放在它们旁边的同一文件夹中来解决此问题。
所以我的项目有：
CONFIG *= force_debug_info
QMAKE_CFLAGS_RELEASE += -O2 -MD -Zi
QMAKE_LFLAGS_RELEASE += /INCREMENTAL:NO /DEBUG
