Local Variable of same name in between function update variable failed.

I found a phenomenon similar to cortex-debug issue

#include <stdio.h>
#include <unistd.h>

void function_one() {
    int num = 10;
    printf("function one\r\n");
}

void function_two() {
    int num = 20;
    printf("function two\r\n");
}


int main() {
    printf("hello world!");
    function_one();
    function_two();
    return 0;
}

function_one context:

function_two context:
