Debugging 64位操作系统上Win32程序的错误调试 Windows 7 64位、Visual Studio 2010、控制台C++应用程序、Win32调试配置： #include "stdafx.h" int _tmain(int argc, _TCHAR* argv[]) { char* p = NULL; *p = 1; return 0; }

现在，如果我在x64调试配置中运行相同的程序，一切正常-调试器在第

*p=1

行中断。如何获得Win32程序的正确调试？

调试->异常->Win32异常->c0000005在“抛出”列或整个Win32异常的“抛出”列中勾选框

test2.exe中0x00041378处的首次机会异常：0xC0000005:访问冲突写入位置0x00000000

谢谢，这就成功了。有趣的是，为什么它在没有对x64进行此更改的情况下工作？可能是出于设计，Visual Studio调试器团队必须知道， Unhandled exception at 0x77d915de in test.exe: 0xC0000005: Access violation writing location 0x00000000. ntdll.dll!77d915de() [Frames below may be incorrect and/or missing, no symbols loaded for ntdll.dll] ntdll.dll!77d915de() ntdll.dll!77d8014e() msvcr100d.dll!_heap_alloc_dbg_impl(unsigned int nSize, int nBlockUse, const char * szFileName, int nLine, int * errno_tmp) Line 504 + 0xc bytes C++ >ffffffff() 'test.exe': Loaded 'C:\tmp\test\Debug\test.exe', Symbols loaded.
