C語言結構體賦值問題

【問題描述】

       以前的系統參數用一個結構體變量tempBasicInfo來保存，成員類型有：uint8_t、uint16_t、結構體，結構體成員爲uint8_t、uint16_t；今天須要添加一系列參數，用了一個uint8_t和三個uint8_t數組；之前配置完tempBasicInfo後會將其賦給常駐的stBasicInfo: 

    stBasicInfo = tempBasicInfo;

    增長數組成員後，編譯無錯，可是調試時出現異常，如：斷點不停，或是有時單步能夠，忽然某一步直接run了；

【問題處理】

     查了半天，才定位到這裏，用memcpy替代後，正常。謹記之~！！！
