I'm running "make check" with the 1.10.0 release of HDF5, and seeing these failures:

   ./use_append_chunk     *FAILED*
   ./use_append_chunk -z 256                       *FAILED*
   ./use_append_chunk -z 256 -y 5                  *FAILED*
   ./use_append_mchunks -z 256                     *FAILED*

I listed the details below for one case, the others are similar.
The errors happen with the GCC, Intel & PGI compilers, using MVAPICH2 or OpenMPI, so if it's an issue with my software stack, it would have to be deeper than these.
The other cases passed:

   ./use_append_chunk -f /tmp/datatfile.1160 PASSED
   ./use_append_chunk -l w                          PASSED
   ./use_append_chunk -l r                          PASSED
   ./use_append_mchunks                             PASSED
   ./use_append_mchunks -f /tmp/datatfile.1160      PASSED
   ./use_append_mchunks -l w                        PASSED
   ./use_append_mchunks -l r                        PASSED
   ./use_append_mchunks -z 256 -y 5                 PASSED

I don't see these tests being run with HDF5 version 1.8.16, though, so is it possible that the they are not formulated correctly?
Thanks,

                    Carl Ponder
