C - Segmentation fault passing char pointer to a function

I am getting a segmentation fault when I call an array to mark the bit position of the corresponding bit position in an unsigned int set[9] with its index in the global names array names[320][30]. When I run the program, I use ./a.out < data.dat and load a list of 320 words in a list. None are more than 30 characters.

Also, typedef unsinged int Set[10];

Here is the code where I call the addName2Set function

//add name to unsigned int set
void addName2Set(Set set, char *key){
    int index;

    //binary search to get index for key
    index = binarySearch(names, key, 0, 319);
    //call add2set to add index to set
    add2Set(set, index);
}

Here is add2Set

//add value passed to set passed
void add2Set(Set set, int index){
  int element, position;

  //find which element, set[element] of set index is in
  element = findArrayElement(index);

  //convert index to bit position 0-31 in set[element]
  position = findElementPos(element, index);

  //in set[element], set bit position 'position' to 1
  set[element] = set[element] | (1 << position);
}

Here is the findArrayElement and findElementPos function

//for unsigned int set[i], return i
int findArrayElement(int index){
  //index range [j,i]
  int i;
  int j=0;
  //element in set array
  int element;

  //loop through [j,i], return element if range true
  for(i=31; i<320; i+=32){
    if(i <= i && index >= j){       
      return element;
    }
    j+=32;
    element++;
  }
}

//find bit position 0-31 corresponding to index
int findElementPos(int element, int index){
    int j;
    int position;

    j = element*32;
    position = index - j + 1;

    //return bit position
    return position;
}

And finally here is where I call the addName2Member function

//declare key pointer
char *key = (char*)malloc(30);

//set search word to pointer key
strcpy(key, "clean");

//addName2Set
addName2Set(set1,key);

Anyone see why there would be a segmentation fault when I run the program? "Clean" is the first word in the data.dat list.

Here are the results from valgrind
