Merge pull request #2321 in HDFFV/hdf5 from ~DYOUNG/werror:reduce-werror-diffs-3 to develop

* commit 'f19e06b59ee53f17465a7b5974c25c3245a40d9a':
  testpar/t_2Gio.c: Fix a typo that I think was introduced by a         previous warnings PR.  An array element was assigned to         itself---shape[2]Â =Â shape[2];---instead of being assigned to         chunk[2].
