The memory leak seems to be related to string concatenation in the
getter for the Text property.
A getter like this is enough to get the leak:
function TBar.GetTextStr: String;
  Result := 'X';
  Result := Result + 'Y';

If the initial assigment to Result is an empty string, then no leak occurs.

I'll report it in the bugtracker.
