我使用以下代码在异常上遍历堆栈(注意:必须发布时运行它，以便正确地将堆栈跟踪的所需输出接收到控制台，而不是在调试模式下，否则它只会显示弹出式)：

#include "stdafx.h"
#include <process.h>
#include <iostream>
#include <Windows.h>
#include "dbghelp.h"

using namespace std;

#define TRACE_MAX_FUNCTION_NAME_LENGTH 1024
#define TRACE_LOG_ERRORS FALSE

void function2()
{
    int a = 0;
    int b = 0;
    throw new exception;
}

void function1()
{
    int a = 0;
    function2();
}

void function0()
{
    function1();
}

static void threadFunction(void *param)
{
    function0();
}

输出：

Wrote a dump.

问题是，上面的跟踪只包含line: 135，它对应于对threadFunction中的function0();的调用。但是，作为堆栈跟踪的一部分，我希望它包括line: 29，它在其中执行throw new exception;。为什么它不把它作为堆栈跟踪的一部分呢？我如何使它也包括堆栈跟踪的这一部分？FatalExceptionFilter，但这是不好的，因为它有自己的警告，因为它必须在任何地方使用，我想要一个顶级的解决方案。我想捕捉所有顶级异常，我想知道它们到底是在哪里抛出的。

这个代码是在Windows 8.1 64位计算机上运行的。它是一个在发布版build/platform x64下编译的MSVC++控制台应用程序。

Update：我已经使用_set_se_translator方法和Petr的建议尝试了以下内容，但是它似乎仍然不想工作。实际上，零异常的除法被抛出时不被处理，没有什么处理它：

编辑：在与OP的作者进行了广泛的讨论之后，我们找到了在调用堆栈跟踪中只有最顶层函数function0()才“注册”时“意外”行为的解释。事实上，正如在注释部分早期推测的那样，这是因为所有其他函数都会在发布版构建中内联。用解密规范装饰所有函数，确保它们不是内联的。在这种情况下，将获得预期的调用堆栈跟踪.下面描述的处理C++/SE异常的方案仍然有效，尽管它无助于OP作者无法更改生产代码的问题，而且只能处理未处理的异常。编辑的结束.

只是在评论的部分太长之前做出一个快速的回答。

检查这条线是否有一个堆栈跟踪例程，该例程还允许您从.map文件中获取函数的名称。
DbgHelp.dll中的函数是单线程的，应该在整个过程中调用一次。这意味着::SymSetOptions(SYMOPT_UNDNAME | SYMOPT_DEFERRED_LOADS);、::SymInitialize(::GetCurrentProcess(), 0, 1);和::SymCleanup(::GetCurrentProcess());应该分别在main()的开头和结尾被调用。
要跟踪C++异常的调用堆栈，可以将堆栈跟踪放在自定义C++异常类构造函数中。这样，在构建throw MyException();和MyException对象时，可以跟踪调用堆栈。
为了在SE被引发时(例如，除以零)，使用_set_se_translator()并创建一个translator函数，该函数抛出一个C++异常类对象，并将EXCEPTION_POINTERS *传递给它的构造函数。然后使用EXCEPTION_POINTERS *保存线程上下文来跟踪调用堆栈。

基本上，您有一个定制的C++异常类，其构造函数看起来如下(警告:没有测试)：

class MyException {
 public:
  MyException(EXCEPTION_POINTERS * _ptr = nullptr) {
   ::CONTEXT context_;
   ::ZeroMemory( &context_, sizeof(::CONTEXT));
   CONTEXT * pcontext_ = &context_;

   if(_ptr) pcontext_ = _ptr->ContextRecord; // in case of SE translator
   else ::RtlCaptureContext(&context_); // in case of 'throw MyException();'

   // Call-stack tracing using pcontext_ here...
  }

  // Other stuff for MyException class...
 };

因此，要将它与throw和_set_se_translator一起使用，您可以使用

throw MyException();

和

void my_translator(unsigned int, EXCEPTION_POINTERS * _ptr){
 throw MyException(_ptr);
}

使用最近的dbghelp.dll (以及相应的最近的MSVC)，您也可以找到内联帧的功能/位置。

在StackWalk()之前添加以下内容

DWORD frameCount = 0;

将其添加到StackWalk()循环(但在SymFromAddr()之前)：

DWORD64 addr = frame.AddrPC.Offset;
// make sure the location of the calling function is reported, and not of the next statement
if (frameCount != 0 && addr != 0) addr--;
frameCount++;
// number of inlined frames, if any
DWORD inlineTrace = SymAddrIncludeInlineTrace (process, addr);
if (inlineTrace != 0)
{
    DWORD inlineContext, frameIndex;
    // the inline context is needed
    if (SymQueryInlineTrace (process, addr, 0, addr, addr, &inlineContext, &frameIndex))
    {
        for (DWORD i = 0; i < inlineTrace; i++)
        {
            DWORD64 displacement64 = 0;
            // similar to SymFromAddr()
            if (SymFromInlineContext (process, addr, inlineContext, &displacement64, symbol))
            {
                DWORD displacement = 0;
                // similar to SymGetLineFromAddr64()
                if (SymGetLineFromInlineContext (process, addr, inlineContext, 0, &displacement, line))
                {
                    printf("inline: at %s in %s: line: %lu: address: 0x%0X\n",
                            symbol->Name, line->FileName, line->LineNumber, symbol->Address);
                }
            }

            // raise to get inline context of next inlined frame
            inlineContext++;
        }
    }
}

我在这个页面上绊倒了，因为我一直很难从异常中获得正确的文件名/行号，尽管手动创建了产生正确堆栈跟踪的致命错误。结果只是简单地包括了PDB，确保了所有调用堆栈尽可能准确。
