今天在调试程序的时候出现以下运行是错误:
“Run-Time Check Failure #2 - Stack around the variable 'szNum' was corrupted. ”
随后在“yin_xiaogang”的Blog上发现了这个问题的解决方法:

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
#include
#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;
}
