vs中 Stack around the variable 'XXX' was corrupted.

把 project->配置屬性->c/c++->代碼生成->基本運行時檢查 爲 默認值 就不會報本異常。具體緣由正在研究中。。。
若是改成其餘就有exception。
exception有時是有道理的
// 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
}
這個也會致使上述exception。

問題描述：
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;
}
