                 * The cause for the file size differences:
                 *   When the file is initially created with persisting free-space and with
                 *   (earliest, latest) libver bounds, the file will have version 2 superblock
                 *   due to non-default free-space handling.  As the low bound is earliest,
                 *   the library uses version 1 object header when creating the superblock
                 *   extension message.
                 *   When the file is reopened with the same libver bounds, the file's low
                 *   bound is upgraded to v18 because the file has version 2 superblock.
                 *   When the library creates the superblock extension message on file close,
                 *   the library uses version 2 object header for the superblock extension
                 *   message since the low bound is v18.
                 *   This leads to the discrepancy in file sizes as the file is persisting
                 *   free-space and there is object header version differences.
                 *  The fix:
                 *    Set libver bounds in fapl to (v18, latest) so that the file created in the
                 *    test routines will have low bound set to v18.  This will cause the
                 *    library to use version 2 object header for the superblock extension
