EXC BAD ACCESS TREAD in c

it gives me EXC_BAD_ACCESS (code=1, address=0xc) at the strcmp in the while (strcmp(parola, temp->next->parola) picture of the xcode debugging session

if (temp->next != NULL){
        if (strcmp(temp->next->parola, "\0") != 0 && strcmp(parola, "\0") != 0){
            while (strcmp(parola, temp->next->parola) != 0){
                if(temp->next != NULL){
                    if (strcmp(temp->next->parola, "\0") != 0 && strcmp(parola, "\0") != 0){
                        temp = temp->next;
                    } else {break;}
                } else {break;}
            }
        }
    }

if (temp->next != NULL){
    if (strcmp(temp->next->parola, "\0") != 0 && strcmp(parola, "\0") != 0){
        while (strcmp(parola, temp->next->parola) != 0){
                    if (strcmp(temp->next->parola, "\0") != 0 && strcmp(parola, "\0") != 0){
                        temp = temp->next;
                if(temp->next != NULL){
                    } else {break;}
                } else {break;}
            }
        }
}
