大佬教程收集整理的这篇文章主要介绍了linux – GDB核心转储：通过build-id查找可执行文件，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

但是,当我刚启动gdb并加载核心文件时,不会加载任何调试符号.
(gdb) core-file core [New Thread 10822] [New Thread 10812] Core was generated by `/usr/bin/executable'. Program terminated with signal 6,Aborted. #0 0xb7790424 in __kernel_vsyscall ()
使用strace运行gdb表明它甚至没有尝试找到它们.核心文件包含build-id,所以我猜gdb应该能够找到它…
