Question

任何人都可以請幫我理解這個錯誤信息嗎？

任何人都可以幫我解決這個問題嗎？

非常感謝。

Answer 1

看起來您正在編寫的代碼（？）會嘗試訪問您無權訪問的內存。

./kprank_new3_norm: munmap_chunk(): invalid pointer: 0x00000000096912d0 *** 

並可根據您的GDB輸出你也許試圖關閉沒有打開，或者可能已經關閉的文件，因爲在它的範圍不是更多？沒有看到你的代碼，我很難說。

Answer 2

它看起來像你打電話給刪除或免費的東西已被刪除或無效/損壞。

嘗試在valgrind下運行，如果原因在您已有的堆棧跟蹤中不明顯。

Answer 3

根據我的經驗，有時候，不能解決每個依賴項的makefile（例如，條目不依賴頭文件的排序）會導致加密問題，也就是說可能會更改類簽名，而不是重新編譯所有內容這取決於那個班，導致許多種記憶麻煩。

那麼，也許乾淨和重新編譯？

Answer 4

std :: map的dtor在關閉時崩潰。你是否以一種可能破壞其內部狀態的無效方式填充地圖？
