任何想法爲什麼在完成第1-9頁時,該程序將無法從第#12頁下載圖像?我真的不知道我該如何調試。也許有一個wget的問題,當它沒有找到第一個圖像? http://img717.imageshack.us/img717/7954/white2u.png在某些情況下,分段錯誤(核心轉儲)

它看起來像你開始用12頁你的意思是第24頁? – Hogan 2014-12-05 20:43:10
不,我在快速發現問題時將代碼更改爲開始。在第10頁中也有同樣的問題,但不是第一個圖像。 – Arturo 2014-12-05 20:44:09
那麼哪條線路故障? – Hogan 2014-12-05 20:45:04
