浅析stack around the variable was corrupted（含转的文章）

我在完成老师布置的课程设计时遇到了这样的错误：stack around the variable “XX” was corrupted.，中文翻译就是“在变量XX周围的堆栈已损坏”。后面在上网看了很多技术资料，发现大多数网站都有这样的文章：

Code:

把 project->配置属性->c/c++->代码生成->基本运行时检查为默认值就不会报本异常。具体原因正在研究中。。。
如果改为其他就有exception。
exception有时是有道理的
// step 1
STRINGC2& STRINGC2::operator += (const char x)
{
// if (x == 0) return *this;
char ptr[1]; // max is 1 digit
ptr[0] = x;
ptr[1] = '/0';
*this += ptr; // off to step 2 and back
return *this; // step 4 crash
}
这个也会导致上述exception。
问题描述：
Problem
The following error message occurs when building on Test RealTIme environment with the cvisual7 TDP?
Run-Time Check Failure #2 - Stack around the variable 'xxx' was corrupted.
Cause
Stack pointer corruption is caused writing outside the allocated buffer in stack memeory.
Solution
This kind of error is detected by setting /RTC1 compiler option from menu Project -> Settings -> Configuration properties -> Build -> Compiler -> Compiler flags when using TDP cvisual7 in IBM® Rational® Test RealTime environment.. This 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;
}

我也尝试了把“project->配置属性->c/c++->代码生成”改为基本运行时检查，就没有这样的错误了。关于MSDN的解释是在堆栈外面读写某数据。错误是名为RTC1的编译器检测的。又看了更多的技术文章，发现这样的错误是程序员在项目到了一定大的时候，它占用的堆栈量就比较大。我也深有体会。因为自己本来编写一个类，运行时没有错，但是在添加成员属性的时候，在其它方式不变的情况下就容易发生这样的错误。所以据此我猜应该是VS2005（2008）在内部就限定了堆栈的大小，当项目足够大的时候，就会溢出。
