void fun1(int a, int b)
{
   char buf_fun1[4];
   ......
}

void fun2(int a, int b , int c)
{
    char buf_fun2[100];
    ...
}

在调用fun1,fun2时它们的stack分布有一些差异.

fun1:
           stack(低地址)  top of buf_fun1
                           fsp
                           ret
                           a
                           b
            stack(高地址)  ..
fun2:
           stack(低地址)  top of buf_fun2
                           有其他在top of buf_fun2和fsp之间??why????
                           fsp
                           ret
                           a
                           b
                           c
            stack(高地址)  ..

                          

      望大虾指点                     

1.跟源代码注释没有关系
2.如此简单的代码，函数调用，堆栈不会出现问题
