关于stack around the variable “” was corrupted问题

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:
- 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;
- }
把“project->配置属性->c/c++->代码生成->基本运行时检查 设置为默认值,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。
