聂树斌被宣判无罪案:此程序在WINTC上编译成功 在VC++上却显示一个错误

#include "stdlib.h"
#define max_size 30
typedef struct {
int num;
int code;
}ElemType;
typedef struct{
ElemType *elem;
int length;
int listsize;
}SqList;
main()
{SqList L;
int n,i,e,t,a,m;
printf("This Joseph designed by:Computer 4;3104006615,wu sheng xing\n");
do{n=0;t=0;
L.elem=(ElemType*)malloc(max_size*sizeof(ElemType));
if(!L.elem)return;
L.length=0;
L.listsize=max_size;
printf("input the %d's num,input 0 to end:",n+1);
scanf("%d",&e);
while(e!=0)
{L.elem[n].code=e;L.elem[n].num=n+1;n++;

n--;L.length--;
}
printf("\npress 1 to countinue press 0 to end\n");
scanf("%d",&a);

求助！！
