当你在分析一些dmp文件时，可能会发现下面的异常信息：
0:000> .exr -1 ExceptionAddress: 00000000 ExceptionCode: 80000003 (Break instruction exception) ExceptionFlags: 00000000 NumberParameters: 0
实际上我们没有在代码中设置任何硬代码断点，所以在google中搜索这个异常，有人说这个异常可能是由于堆损坏引起的。所以我的问题是，除了硬代码断点、调试时的手动断点、堆损坏之外，是否还有其他原因导致此异常？
另一个问题是，我试图使用应用验证器来检查堆损坏，我知道它是如何工作的，应用验证器将在堆损坏时触发中断指令异常。但目前，我运行没有应用验证程序，谁会提出中断指令异常？
我们的应用程序是一个Visual Studio包。
以下是结果来自!analyze -v

在托管堆栈中，存在一个显式错误Microsoft.VisualStudio.NativeMethods.ThrowOnFailure。。但这意味着com异常导致中断指令异常？
!analyze似乎只是转储托管级别，com异常可能是托管级别中的最后一个错误。
我还从google上搜索了一些关于中断和异常的信息，通常中断指令异常可以在以下条件下触发：1。硬代码中断请求，如：uu asm int 3（asm）、System.Diagnostics.Debugger.Break（C 35;）、DebugBreak（）（WinAPI）。2。操作系统启用内存运行时检查，就像应用程序验证程序在堆损坏、内存溢出后会触发一样。三。编译器可以有一些配置来启用未初始化的内存块和函数结束时应填充的内容（在重新运行..后的空白区域）。例如，如果启用/GZ，Microsoft VC编译器可以填充0xCC。0xCC实际上是asm int 3的操作码。所以如果某个错误导致应用程序运行到这样的块中，就会触发一个断点。
对吗？如果是这样，我认为应用程序验证程序应该是找到根本原因的最佳选择。
