That was a static analyzer report, so I don't know how to run this code or have any input data. But the problem is in syntactically inconsistent code: the pointer `Parent` is dereferenced to call a method, and in its parameter it is checked on NULL. This check should be either placed before first dereference, or removed completely as redundant.
