为什么执行无效指令不会终止我的程序? [英] Why executing invalid instruction does not terminate my program?

问题描述

我在VC ++中编程，我输入了无效的指令，例如

*(long *)0 = 0;

在我的对话框的窗口进程中.对于某些消息，例如VM_INITDIALOG，此指令将导致按预期在位置0X00000000写入访问冲突.但是在大多数消息(例如WM_PAINT等)中放置任何无效的指令并不会终止我的程序，这使我不会注意到程序中的错误.谁能告诉我这是为什么?
当我在32位平台上使用Windows XP和Windows Vista时，此问题并未解决.
我在Windows7 64bit上使用Visual Studio 2008 32bit，而我的硬件是HP笔记本DV6-2020EV

I program in VC++, I put an invalid instruction such as

*(long*)0=0;

In the window proc of my dialogs. for some messages such as VM_INITDIALOG this instruction causes an access violation writing at location 0X00000000 as expected. But putting any invalid instruction in most messages such as WM_PAINT,... does not terminate my program and this causes me not to notice bugs in my program. can anyone tell me why is this?
This problem did not accure when I used Windows XP and Windows Vista on 32bit platforms.
I use Visual Studio 2008 32bit on Windows7 64bit and my hardware is HP notebook DV6-2020EV
