Run-Time Check Failure #2 - Stack around the variable 'szNum' was corrupted

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：

Stack around the variable was corrupted
2008-07-15 15:42

[b]Problem[/b] 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. [b]Cause [/b] Stack pointer corruption is caused writing outside the allocated buffer in stack memeory. [b]Solution[/b] 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; } [b]Related information[/b] IBM Rational TestRT Support http://www-1.ibm.com/support/docview.wss?rs=945&context=SSSHUF&context=SSSTY3&context=SSCSNZN&context=SSSTWP&q1=Stack+around+the+variable+was+corrupted&uid=swg21211974&loc=en_US&cs=utf-8&lang=en vs 2005 改一下 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 那个异常 如果 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
