The array of dirstat_file contained in the dirstat_dir structure is not freed after the processing ends. Unfortunately, the member that points at the array, .files, is incremented as the gather_dirstat() function recursively walks it, and this needs to be plugged by remembering the beginning of the array before gather_dirstat() mucks with it and freeing it after we are done. We can mark t4047 as leak-free. t4000, which is marked as leak-free, now can exercise dirstat in it, which will happen next.
