调试时使用MinidumpWriteUp()Win32 API时出现异常

我从C++/CLI中的进程“1”派生出一个进程“2”。当两个进程都在运行时,进程“1”会终止进程“2”(按设计)。我的目标是在杀死“2”之前制作一个小型垃圾场。

这是我的代码:

// mpProcess started with System::Diagnostics::Process... etc.
System::IO::FileStream^ fs = gcnew System::IO::FileStream("MyPath.dmp");

MiniDumpWriteDump( mpProcess->Handle.ToPointer(), mpProcess->Id, fs->SafeFileHandle->DangerousGetHandle().ToPointer(), MINIDUMP_TYPE::MiniDumpNormal, nullptr, nullptr, nullptr);
fs->Close();

当我从命令行启动进程“1”,而不将其附加到调试器时,它会正常运行,启动进程“2”,然后转储它,然后终止它。

当我在调试器中启动进程“1”时,我得到2-3 AccessViolationException 当我跨过电话 MiniDumpWriteDump ,但如果我单击“继续”,一切都会正常,并生成转储文件。

怎么回事?我的设计有什么问题吗?请注意,这是我第一次使用这个API,24小时前我甚至不知道我可以转储这样的文件;-)!我将非常感谢您的帮助,以提高我的技能与转储文件。

编辑1 添加了异常信息:

以下是我得到的信息:

在MYProg中的0x000007FED860FD31(mscordacwks.dll)处引发异常。exe:0xC0000005:访问冲突读取位置0x0000000000。

如果有此异常的处理程序,程序可以安全地继续。

编辑2 添加了一个代码片段和堆栈跟踪

过程1 :杀手

// Process1.cpp : main project file.

#include "stdafx.h"

#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <dbghelp.h>

using namespace System;

int main(array<System::String ^> ^args)
{
     Console::WriteLine(L"Hello, I'm Process1! I'll \"minidump\" Process2 then kill it!");

    System::Diagnostics::Process^ p = gcnew System::Diagnostics::Process();

    p->StartInfo->FileName = "Process2.exe";
    p->Start();

    System::Threading::Thread::Sleep( 3000 );

    System::IO::FileStream^ fs = gcnew System::IO::FileStream( "minidump.dmp", System::IO::FileMode::Create );

    MiniDumpWriteDump( p->Handle.ToPointer(), p->Id, fs->SafeFileHandle->DangerousGetHandle().ToPointer(), MINIDUMP_TYPE::MiniDumpNormal, nullptr, nullptr, nullptr );

    fs->Close();

    p->Kill();

    return 0;
}

过程2 字体“被抛弃”

// Process2.cpp : main project file.

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)
{
    Console::WriteLine(L"Hello, I'm Process2! I'm waiting to be killed by Process1!");

    // Do nothing, wait to be killed
    while ( true )
    {
        System::Threading::Thread::Sleep( 1000 );
    }

    return 0;
}
