Thank you for the report.  That bug was fixed in coreutils-5.94:

* Major changes in release 5.94 (2006-02-13) [stable]
  ...
** Bug fixes
  ...
  fts-using tools (chmod, chown, chgrp, du) no longer fail due to
  a double-free bug -- it could be triggered by making a directory
  inaccessible while e.g., du is traversing the hierarchy under it.

The latest stable release is 5.96.
