VS2008中Run-Time Check Failure #2 - Stack around the variable 'xxx' was corrupted 错误解决方法

问题 ：

在用VS2008写一段代码，算法都没有问题，但是调试的时候发现出了main之后就报 Stack around the variable 'xxx' was corrupted 的错误，后来发现是数组越界造成的。测试下面类似情形的代码：

#include <iostream> using namespace std; int main() { int i, j, tmp; int a[10] = {0};// 0, 1, ... , 9 for(i = 0; i < 10; ++i) { a[i] = 9 - i; } for(j=0; j<=9; j++) { for (i=0; i<10-j; i++) { if (a[i] > a[i+1])// 当j == 0时，i会取到，导致a[i+1]越界 { tmp = a[i]; a[i] = a[i+1]; a[i+1] = tmp; } } } for(i=1;i<11;i++) { cout << a[i]<<endl; } system("pause"); return 0; } 

出现下图 Debug Error:
Run-Time Check Failure #2 - Stack around the variable 'a' was corrupted

 

原因 ：
Stack pointer corruption is caused writing outside the allocated buffer in stack memory.

解决方法 ：
This kind of error is detected by setting /RTC1 compiler option from menu 属性页(Alt+F7) -> 配置属性 -> C++ -> 代码生成 -> 基本运行时检查
有以下几个选项：
(1) 默认值
(2) 堆栈帧 ( /RTCs )
(3) 未初始化的变量 ( /RTCsu )
(4) 两者 ( /RTC1, 等同与 /RTCsu )
(5) <从父级或项目默认设置继承>

方法1 ：修改数组越界的错误。
方法2 ：设置为 (1) 默认值，就不再进行 stack frame run-time error checking。

Using /RTC1 compiler option enables stack frame run-time error checking. For example, the following code may cause the above error messge.
#include <stdio.h> #include <string.h> #define BUFF_LEN 11 // 12 may fix the Run-Time Check Failure #2 int rtc_option_test(char * pStr); int main() { char * myStr = "hello world"; rtc_option_test(myStr); return 0; } int rtc_option_test(char * pStr) { char buff[BUFF_LEN]; strcpy(buff, pStr); //cause Run-Time Check Failure #2 - Stack around //the variable 'buff' was corrupted. return 0; }
