Visual C++ 中编译完全正确，但无法执行~
无错误和警告~
可是一旦运行~
弹出警告提示框，上面文字如下：

Debug Assertion Failed!

Program:C:\Debug\main.exe
File:dbgheap.c
Line:1044

Expression:_CrtIsValidHeapPointer(pUserData)

For information on how your program can cause an assertion
failure,see the Visual C++ documentation on asserts.

(Press Retry to debug the application)

请高手蝈蝈们指点一下哈~
