Seg Fault occurs while malloc-ing - c

Question

This function is a part of program which will gain statistics about books (amount of specific letters, words etc.). Thing is that segmentation fault appears when trying to malloc:
*wordArray[arrayIndex] = malloc(sizeof(***wordArray)*(wcslen(newWord)+1));
after reallocing whole array
*wordArray = realloc(*wordArray, (arrayIndex+1)*sizeof(**wordArray));
I know that realloc isn't really efficent but the most important thing at the moment is to understand why it doesn't work at all. Thanks a lot.
