C Linked List from Array

In the function, I created an array of size two which will hold two PolyTerms. Then, within the function, i created a List. After that, i want to pass the array elements into the List as linked list.

I'm getting an error after the if statement head->next = nodePtr; (Bad Access).

Thanks.

Part of my code:

struct Fraction {
    int num;
    int denom;
};

struct PolyTerm {
    int ex;
    struct Fraction coe;
};
typedef struct PolyTerm PTerm;
typedef struct PolyTerm* PTermPtr;

struct PolyListNode {
    PTermPtr termAddr;
    struct PolyListNode* next;
};
typedef struct PolyListNode PList;
typedef struct PolyListNode* PNodeAddr;
typedef struct PolyListNode* PolyList;

PolyList sortPoly(void);

PolyList sortPoly() {

    int arraySize = 2;
    int i = 0;

    //Array of PTermPtr. Each element holds ex, num and denom.
    //Populating 2 elements for arrayTerm

    PTermPtr arrayTerm;
    arrayTerm = (PTermPtr) malloc(arraySize);
    ((arrayTerm) + 0)->ex = 2;
    ((arrayTerm) + 0)->coe.num = 2;
    ((arrayTerm) + 0)->coe.denom = 2;

    ((arrayTerm) + 1)->ex = 3;
    ((arrayTerm) + 1)->coe.num = 2;
    ((arrayTerm) + 1)->coe.denom = 2;

    PNodeAddr nodePtr; //To create nodes
    PolyList head = 0; //New List
    PNodeAddr current; //To store Address of List Head
    current= head; //Store address of head of list

    while (i < arraySize) {

        nodePtr = (PNodeAddr) malloc(sizeof(PList));
        nodePtr->termAddr = (arrayTerm + i);
        nodePtr->next = 0;

        if (current == 0) {
            head->next = nodePtr; //ERROR. Bad Access
        } else {
            while (current != 0) {
                current = current->next;
            }
            current->next = nodePtr;
        }
        i++; 
    }
    free (arrayTerm);
    return head;
}
