求查此程序在最后为什么会执行错误
#include <stdio.h>
#include <stdlib.h>
typedef struct LNode
{int data;
struct LNode *next;
}Lnode,*Linklist;
Linklist creat(int m)
{

Linklist L,p,h;
L = (Linklist)malloc(sizeof(Lnode));
h = L;
for(i = 1;i <= m;i ++)
{
p = (Linklist)malloc(sizeof(Lnode));
p -> data = i;
h -> next = p;
h = p;
}
h -> next = L -> next;
p = h -> next;
return L;
}
void Delete(int m,int s,int n,Linklist L)
{
int i;
Linklist p,h,q;
p = L;
if(m < 1)
{
printf("Game Can not Carry On.\n");
}
else{
for(i = 1;i < s;i ++)
{
p = p -> next;
}
while(p)
{
for(i = 1;i < n;i++)
{
p = p -> next;
}
q = p -> next;
printf("%d ",p -> next -> data);

[解决办法]
表示调试无果，问了一个大神，说是不要随便写while（p），事实也证明确实是这个的问题，大神可否解释下为什嘛
