memset sets every byte with the specified value, and int is a 4 byte value. So for instance, memset(mini, 250, sizeof(mini)); would set each element of the array as $$$-84215046$$$ instead of $$$250$$$. These values are used as indices later in your code, leading to out-of-bounds error.

Replace memset with a loop to initialize the array elements. That should fix it
