SWITCH语句仿真时为什么会出错？

最近在调程序，遇到SWITCH语句，用仿真器去调试。以下程序编译没问题，在ADS1.2、RVDS2.2、KEIL ARM3.05A、KEIL C51下仿真都会出错，唯有在ICCAVR 6.3编译后用AVRSTUDIO仿真是对的。难道D版的编译器有问题？
void Lcd_Init(unsigned char i );

main(void)
{

        unsigned char i=5;
        Lcd_Init(i);


         i=0x00;
         return 0;
}

void Lcd_Init(unsigned char i)
{
    unsigned char cc;
    switch(i)
    {
    case 1:
      {
        //gg=(unsigned char (*)[20])aa+1;
        cc=9;
        break;
       }
    case 2:
       {
         //gg=(unsigned char (*)[20])aa;
         cc=9;

         break;
        }

    case 3:
        {
          //gg=(unsigned char (*)[20])aa;
          cc=9;
          break;
        }
    case 4:
        {
          //gg=(unsigned char (*)[20])aa;
          cc=9;
          break;
        }
    case 5:
        {
          //gg=(unsigned char (*)[20])aa+2;
          cc=9;
          break;
        }
    default:
    break;
    }
}
