Visual Studio：“没有调试器的目标代码类型的可执行代码与此行相关联”

Question

我正在尝试调试我注入另一个进程的dll。

这是我的代码：

// dllmain.cpp : Defines the entry point for the DLL application.
#include "stdafx.h"
#include <iostream>
#include <thread>
#include "jvmti/jni.h"

bool started = false;

BOOL APIENTRY DllMain(HMODULE hModule, DWORD  ul_reason_for_call, LPVOID lpReserved)
{
    std::cout << "Started?" << std::endl;

    if(ul_reason_for_call == DLL_PROCESS_ATTACH)
    {
        std::cout << "Attached to process!" << std::endl;

        if(!started)
        {
            started = true;
            void startClient();
            std::thread startThread(startClient);
        }
    } 
    else if(ul_reason_for_call == DLL_PROCESS_DETACH)
    {
        std::cout << "Detached from process!" << std::endl;
    }

    return TRUE;
}

typedef jint(CALLBACK* GetJvmsFunc)(JavaVM**, jsize, jsize*);

void startClient()
{
    HMODULE javaHandle = GetModuleHandle(L"jvm.dll");
    GetJvmsFunc getJvmsFunc = reinterpret_cast<GetJvmsFunc>(GetProcAddress(javaHandle, "JNI_GetCreatedJavaVMs"));

    JavaVM** vmBuf = NULL;
    jsize* numberOfVms = NULL;
    jsize bufLen = 1;

    long* numOfVms = static_cast<long*>(numberOfVms);
    jint funcStatus = getJvmsFunc(vmBuf, bufLen, numberOfVms);

    printf("Function status: %ld\n", funcStatus);
    printf("Number of VMS: %p\n", (void*)numberOfVms);
}

现在每当我运行此代码时，我都会注入崩溃的进程。为了诊断这个，我在这个方法的第一行放了一个断点，如下所示：

现在我看不出这个代码怎么会被击中？我启动一个应立即调用startClient()函数的线程。

我还尝试清理并重建我的项目，删除所有符号文件，清除符号缓存等等。

我目前唯一的想法是Visual Studio在调试时产生的输出。它没有明确声明它为我的DLL加载符号。这是输出：

是什么导致了这个问题？
