恳请名位高手帮帮忙啊
程序怎么调试都没问题，但就是Runtime error!
到底什么是Runtime error啊？？？我都快郁闷死了!!!

下面是我的C程序代码：
#include<stdio.h>
#include<malloc.h>
#include<string.h>
char f(char c)
{
  switch(c)
  {
    case '1':return '1';
    case '2':
    case 'A':
    case 'B':
    case 'C':return '2';
    case '3':
    case 'D':
    case 'E':
    case 'F':return '3';
    case '4':
    case 'G':
    case 'H':
    case 'I':return '4';
    case '5':
    case 'J':
    case 'K':
    case 'L':return '5';
    case '6':
    case 'M':
    case 'N':
    case 'O':return '6';
    case '7':
    case 'P':
    case 'R':
    case 'S':return '7';
    case '8':
    case 'T':
    case 'U':
    case 'V':return '8';
    case '9':
    case 'W':
    case 'X':
    case 'Y':return '9';
    case '0':return '0';
    case '-':return '#';
    case '\n':return '\0';
    default:printf("Input error!\a");exit(0);
  }
}
void sort(char *s,long n)
{
  char *t;
  int i,j;
  for(i=0;i<n-1;i++)
  for(j=i+1;j<n;j++)
  if(strcmp(s+9*i,s+9*j)>0)
  {
    strcpy(t,s+9*i);
    strcpy(s+9*i,s+9*j);
    strcpy(s+9*j,t);
  }
}
void main()
{
  long n,t=0;
  register long i;

  int j=0,flag=1,*fl;
  char c='\0',*s;
  scanf("%ld",&n);
  getchar();
  s=(char *)malloc(9*n);
  fl=(int *)malloc(n*sizeof(long));
  for(i=0;i<n;i++)fl[i]=0;
  for(i=0;i<n;i++)
  {

    while(c!='\n')
    {
      if(j==3)s[9*i+j++]='-';
      c=getchar();
      if((s[9*i+j]=f(c))!='#')j++;
    }
    c='\0';
    j=0;
  }
  sort(s,n);
  for(i=0;i<n-1;i++)
  {
    if(fl[i]==1)continue;
    for(j=i+1;j<n;j++)
    if(!strcmp(s+9*i,s+9*j))
    {
      t++;
      fl[j]=1;
    }
    if(!t)continue;
    flag=0;
    for(j=0;j<8;j++)
    putchar(s[9*i+j]);
    printf(" %ld\n",t+1);
    t=0;
  }
  if(flag)printf("No duplicates.\n");
  free(s);
}
