1、問題描述，where資訊顯示不詳細，只能看到具體哪個函式錯了，但詳細的資訊看不出來，且list命令顯示的程式碼也完全對不上

Program terminated with signal 11, Segmentation fault.
#0  0x00007f08c919797e in *******::*******(long, int&) () from /home/lib/lib****.so
(gdb) where
#0  0x00007f08c919797e in ******::*****(long, int&) () from /home/lib/lib***.so
#1  0x00007f08c9199642 in *****::****() () from /home/lib/lib****.so

。。。。
#7  0x000000000040869b in main ()

2、查資料說需要加-g選項編譯

使用-g選項編譯，可以產生帶有除錯資訊的目的碼，以便能夠在core檔案中包含除錯資訊，方便gdb跟蹤至原始碼行

Program terminated with signal 6, Aborted.
