iexplore.exe 中的 0x779b29e3 處最可能的例外: 0xC0000005: 讀取位置 0x06bd5392 時發生訪問沖突看堆疊是ntdll里面，沒有任何有用的資訊
uj5u.com熱心網友回復：
崩潰的時候在彈出的對話框按相應按鈕進入除錯，按Alt+7鍵查看Call Stack即“呼叫堆疊”里面從上到下列出的對應從里層到外層的函式呼叫歷史。雙擊某一行可將游標定位到此次呼叫的源代碼或匯編指令處，看不懂時雙擊下一行，直到能看懂為止。有時不將“呼叫函式名字＋各引數值，進入函式后各引數值，中間變數值，退出函式前準備回傳的值，回傳函式到呼叫處后函式名字＋各引數值＋回傳值”這些資訊寫日志到檔案中是無論如何也發現不了問題在哪里的，包括捕獲各種例外、寫日志到螢屏、單步或設斷點或生成core或dmp檔案、……這些方法都不行！ 寫日志到檔案參考下面：
//回圈向a函式每次發送200個位元組長度（這個是固定的）的buffer,
//a函式中需要將回圈傳進來的buffer，組成240位元組（也是固定的）的新buffer進行處理，
//在處理的時候每次從新buffer中取兩個位元組列印
