    void sigfunc(int signo)

    {

        printf("%s(0): %p\n", __func__, __builtin_return_address());

        exit();

    }  

    int b()

    {

        printf("%s(0): %p\n", __func__, __builtin_return_address());

        printf("%s(1): %p\n", __func__, __builtin_return_address());

        while()

        {

            sleep();

        }

    }  

    int a(int temp)

    {

        temp += ;

        printf("%s(0): %p\n", __func__, __builtin_return_address());  

        b();

    int main()

    {

        signal(SIGINT, sigfunc);

        a();  

        return ;

    }  

执行后：

a(): 0x400675

b(): 0x400653

b(): 0x400675

^Csigfunc(): 0x30bda33140

用gdb调试：

gdb e

...

(gdb) l *0x400675

0x400675 is in main (e.c:).

    int main()

    {

        signal(SIGINT, sigfunc);

        a();

        return ;

    }
