This tutorial shows how to debug core dumps created by Linux systems when an application crashes. We will first create a program that causes SIGSEGV at a certain point in time, then run it without debugger to let it crash and produce a dump, and finally open the dump file with VisualGDB ...
2. 在一般Linux系统中,默认是不会产生core dump文件的,通过ulimit -c来查看core dump文件的大小,一般开始是0,可以设置core文件大小,ulimit -c 1024(kbytes单位)或者ulimit -c unlimited。 3. core dump文件输出设置,一般默认是当前目录,可以在/proc/sys/kernel中找到core-user-pid,通过 echo"1" > /proc/sys/...

2dump_stack() 有些时候,只需要在终端上打印一下栈的回溯信息来帮助你调试。这时可以使用dump_stack()。这个函数只在终端上打印寄存器上下文和函数的跟踪线索。if(!debug_check) { printk(KERN_DEBUG “provide some information…/n”); dump_stack(); ...
而函数调用关系,则是根据栈帧结构,从最深层次函数开始,逐层推导出来的。简单来说,就是逐层从栈中获取函数的返回地址,根据返回地址,从ELF的debug信息中找到对应的函数名、代码行号等信息。(函数栈帧结构不是本文重点,篇幅所限,不再赘述,感兴趣的小伙伴可以加我微信CreCoding讨论)。
