gdb调试core文件，where信息不详细

1、问题描述，where信息显示不详细，只能看到具体哪个函数错了，但详细的信息看不出来，且list命令显示的代码也完全对不上

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、查资料说需要加-g选项编译

使用-g选项编译，可以产生带有调试信息的目标代码，以便能够在core文件中包含调试信息，方便gdb跟踪至源代码行

Program terminated with signal 6, Aborted.
#0  0x00007f119a8c05d7 in __GI_raise (sig=sig@entry=6) at ../nptl/sysdeps/unix/sysv/linux/raise.c:56
56        return INLINE_SYSCALL (tgkill, 3, pid, selftid, sig);
