归并排序问题，代码是按照教学视频打的，为什么会出错，显示一些奇奇怪怪的数字

如题，不知道是哪里疏漏了，请各位大神指教

#include<stdio.h>
#include<stdlib.h>

void merging(int list1[],int list1_size,int list2[],int list2_size)
{
    int temp[8],i=0,j=0,k=0;
    while(i<list1_size&&j<list2_size)
    {
        if(list1[i]<list2[j])
        {
            temp[k++]=list1[i++];
        }
        else
        {
            temp[k++]=list2[j++];
        }
    }
    while(i<list1_size)
    {
        temp[k++]=list1[i++];
    }   
    while(i<list2_size)
    {
        temp[k++]=list2[j++];
    }   
    for(int m=0;m<(list1_size+list2_size);m++)
    {
        list1[m]=temp[m];
    }
}
void merge_sort(int k[],int n)
{
    if(n>1)
    {
    int *list1=k;
    int list1_size=n/2;
    int *list2=k+n/2;
    int list2_size=n/2;
    merge_sort(list1,list1_size);
    merge_sort(list2,list2_size);
    merging(list1,list1_size,list2,list2_size);
    }
}

int main()
{
    int a[8]={3,41,52,26,38,57,9,49};
    merge_sort(a,8);
    for(int i=0;i<8;i++)
        printf("%d ",a[i]);
    return 0;
}
