 * The following two test files are generated with older versions

 * testh5stat.sh.in.
 *
 * (1) h5stat_err_old_layout.h5
 *     This file is generated with the 1.6 library so that a file
 *     with a version 2 layout message is created.
 *     Then a "0" is written to the "dimension" field in the layout
 *     message to trigger the error.
 *     This is to verify HDFFV-10333 that h5stat will exit gracefully
 *     when encountered error similar to H5O__layout_decode in the
 *     jira issue.
 *
 * (2) h5stat_err_old_fill.h5
 *     This file is generated with the 1.4 library so that a file
 *     with an old fill value message is created.
 *     Then an illegal size is written to the "size" fild in the
 *     fill value message to trigger the error.
 *     This is to verify HDFFV-10333 that h5stat will exit gracefully
