A semicolon is missing

Let's see a joke first ：

I'm a programmer , One day I was sitting on the side of the road, drinking water and checking bug. Then a beggar sat down beside me , Start begging , I feel pathetic , I gave it to him 1 Yuan , Then debug the program . He may have a bad business , It's boring to see what I'm doing , And then after a while , He said quietly , A semicolon is missing here .

----------------------

Before, this joke was just a look , I thought that without a semicolon, the compiler immediately prompted , This scenario is impossible , Until today,

        USART_SendData(MYUSART,*data);
        while(USART_GetFlagStatus(MYUSART,USART_FLAG_TC)==RESET); //<--- Look here , Without this semicolon
        data++;
