 *		When the dataset is closed in H5D_close(), the pointer
 *		to the extensible array struct in the layout message
 *		is copied via H5D_flush_real() before H5D_chunk_dest().
 *		This causes an abort from "Assertion `ea->hdr' failed."
 *		later when the dataset is re-opened and read.

 * Function: test_fixed_array
 *
 * Purpose: Tests support for Fixed Array and Implicit Indexing 
 *
 *	Create the following 3 datasets:
 *	1) extendible chunked dataset with fixed max. dims
 *	2) extendible chunked dataset with NULL max. dims
 *	3) extendible chunked dataset with same max. dims 
 *         (Note that the third dataset is created with bigger size for curr & max. dims 
 *	    so that Fixed Array Indexing with paging is exercised)
 *
 *      Repeat the following test with/without compression filter
 *              Repeat the following test with H5D_ALLOC_TIME_EARLY/H5D_ALLOC_TIME_LATE/H5D_ALLOC_TIME_INCR
 *                      For the old format, 
 *				verify that v1 btree indexing type is used for 
 *				    all 3 datasets with all settings
 *                      For the new format:
 *				Verify that Implicit Index type is used for
 *				    #1, #2, #3 datasets when ALLOC_TIME_EARLY and compression are true
 *				Verify Fixed Array indexing type is used for
 *				    #1, #2, #3 datasets with all other settings
 *
 * Return:      Success: 0
 *              Failure: -1

 * DLS bug -- HDFFV-9672

 *

 *
 * ------------------------------------------------------
 * 
 * Hi,
 * We've found an issue regarding fixed length strings.
 *
 * If we create a chunked dataset of large fixed length strings 
 * (up to 1kb per string) with small chunk sizes (~8 elements per 
 * chunk) then the resulting dataset may not be read later.
 * This only happens if the file is created with LIBVER_LATEST 
 * for the version bounds.
 *
 * Calling H5Oget_info(...) on the dataset results in the following:
 * 
 * H5Dearray.c:250: H5D__earray_crt_context: Assertion 
 * `udata->chunk_size > 0' failed.
 * 
 * Example:
 * void create_data(...) 
 * {
 *    ...
 * 
 *    hsize_t chunks[1] = {8} ;
 *
 *    err = H5Tset_size( tid, 256 );
 *
 *    err = H5Pset_chunk( dcpl, 1, chunks );
 *
 *    H5Dcreate2( fid, "data", tid, sid, H5P_DEFAULT, dcpl, H5P_DEFAULT );
 * 
 *    // write data

 * ------------------------------------------------------
 * 
 * The bug in question turned out to be caused by a failure to update
 * the enc_bytes_per_dim field in the layout if the size of the 
 * underlying type required more bytes to encode than any of the 
 * chunk dimensions.
 *
 * At least in debug builds, the following test code exposes the 
 * failure via an assertion failure.
 *
 * Note that the test code make no attempt to run with different 
 * file drivers, as the bug is in the actual on disk encoding of 
 * the chunk layout.
