segmentation fault

Trie& Trie::operator+= (const string & word){

            }
         else{
              curr = curr->left;
          while (curr->data != word[i]) {
              if (curr->right == NULL){
                TrieNode*node=new TrieNode();
                node -> data = word[i];
                node->right = NULL;
                node->left = NULL;
                curr->right = node;
          }
               curr = curr->right;
          }
         }
        }
        return *this;
}

Someone please help!! This function is giving me segmentation fault!! I'm trying to insert a word.

Use the debugger, it'll show you where you get the segfault, we can't do much without the full implementation of your class.

This is my struct:

struct TrieNode {
     int data;
     bool end;
     TrieNode *left;
     TrieNode *right;
};
