如果是堆疊破壞的話,通過gdb是無法定位的, 可以使用 valgrind等記憶體檢測工具運行你的程式來找問題uj5u.com熱心網友回復：
您好，我通過gdb大概可以了解到，應該是我的行程處于poll函式的這段呈現??狀態，這個時候還出現了*** Error in `./remote-viewer': malloc(): memory corruption: 0x0018a958 ***，我在arm環境下使用valgrind很麻煩，也沒弄成功，不知道還有其他的方法嗎或者還有其他的可能出錯的地方嗎，謝謝uj5u.com熱心網友回復：
malloc(): memory corruption 這個提示就很明確了, 你malloc申請的某段記憶體, 但是這段記憶體的管理結構被破壞了,需要找一下malloc的記憶體的所有操作, 是否有拷貝(包含初始化/列印等)溢位的情況
