创建动态总和直至 eof 时的核心转储

Question

以下代码在某处存在缺陷，当输入 11/12/13 数字时，我收到“中止（核心转储）”警报。怎么了？

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

int main(){
    // sum nums until EOF
    int* array; // pointer to the first element
    int size = 10; // memory for 10 elements
    int i = 0, sum = 0;
    array = malloc(sizeof(int)*10); //get memory
    while(scanf("%d",(array + i))!= EOF){   //read until EOF
        //add element to the sum
        sum += *(array+i);

        //realloc memory
        if(i == size-1){
            size *= 2;          
            array = realloc(array, size);   
        }
        i++;
    }
    free(array);        //free the memory
    printf("%d\n\n",sum);   //print sum

    return 0;
}
