I am implementing a function to recursively reverse a linked-list, but getting seg-fault.

typedef struct _node {
   int data;
   struct _node *next;
} Node, *NodeP;

NodeP recursiveReverseList(NodeP first){
   if(first == NULL) return NULL;
   if(first->next == NULL) return head;

   NodeP rest = recursiveReverseList(head->next);
   rest->next = first;
   first->next = NULL;

   return first;
}

Can you please help.

P.S. The iterative version is working fine though. Its not homework. Just practicing C.
