C语言写的程序跑飞了,怎样打印出函数调用链呢?
linux_dev_framework软件包中的trace_exception_test.c就是一个实现演示样例。
该程序有益产生一个内存訪问异常,然后打出调用链。

*/ #include <stdio.h>
#include "debug.h"
#include "trace_exception.h" //以下的代码有益产生一个内存訪问异常
static int a;
int __attribute__((noinline)) gen_SIGSEGV(int *bad_pointer)
{
DBG_PRINT("=="); a = *bad_pointer;
return a;
} int __attribute__((noinline)) SIGSEGV_test(int para)
{
DBG_PRINT("=="); return gen_SIGSEGV(NULL)+para;
} int __attribute__((noinline)) main(int argc, char *argv[])
{
DBG_PRINT("=="); trace_exception_init();
SIGSEGV_test(555);
return 0;
}
执行效果:
[root@localhost ~]# cd linux-dev-framework
[root@localhost ~]# make
...
[root@localhost linux-dev-framework]# ./target/trace_exception_test.exe ***********************
