Bug Fixes since HDF5-1.4.3 Release
==================================
* Fixed bug where the data for several level deep nested compound &
variable-length datatypes used for datasets were getting corrupted when
written to the file. QAK - 2002/04/17

selections when optimized I/O was being performed. QAK - 2002/04/02
* Fixed limitation in h5dumper with object names which reached over 1024
characters in length. We can now handle arbitrarily larger sizes for
object names. BW - 2002/03/29
* Fixed bug where variable-length string type doesn't behave as
string. SLU - 2002/03/28
* Fixed bug in H5Gget_objinfo() which was not setting the 'fileno'
of the H5G_stat_t struct. QAK - 2002/03/27
* Fixed data corruption bug in hyperslab routines when contiguous
hyperslab that spans entire dimension and is larger than type
conversion buffer is attempted to be read. QAK - 2002/03/26

Footnotes: (1) Using mpich.
(2) Using mpt and mpich.
(3) When configured with static-exec enabled, tests fail
in serial mode.
(4) No HDF4-related tools.
(5) Shared libraries are provided only for the C library.
(6) Exception of (5): DLL is available for C++ API on Windows
Known Problems
==============
* Datasets or attributes which have a variable-length string datatype are
not printing correctly with h5dump and h5ls.
* When a dataset with the variable-legth datatype is overwritten,
the library can develop memory leaks that cause the file to become
unnecessarily large. This is planned to be fixed in the next release.
* On the SV1, the h5ls test fails due to a difference between the
SV1 printf precision and the printf precision on other platforms.
* The h5dump tests may fail to match the expected output in some
platforms (e.g. SP2 parallel, Windows) where the error messages
directed to "stderr" do not appear in the "right order" with output
from stdout. This is not an error.
* The --enable-static-exec configure flag fails to compile for HP-UX
11.00 platforms.
* The executables are always dynamic on IRIX64 6.5(64 and n32) and
IRIX 6.5 even if they are configured with --enable-static-exec.
* IRIX 6.5 fails to compile if configured with --enable-static-exec.
* The HDF5_MPI_OPT_TYPES optimization code in the parallel HDF5 will cause
a hang in some cases when chunked storage is used. This is now set to
be off by default. One may turn it on by setting environment variable
HDF5_MPI_OPT_TYPES to a non-zero value such as 1.
* On IA64 systems one has to use -DIA64 compilation flag to compile
h4toh5 and h5toh4 utilites. After configuration step manually modify
Makefile in the tools/h4toh4 and tools/h5toh4 directories to add
-DIA64 to the compilation flags.
* On IA32 ansd IA64 systems, if you use a compiler other than GCC
(such as Intel's ecc compiler), you will need to modify the generated
"libtool" program after configuration is finished. On or around line 102
of the libtool file, there are lines which look like:
# How to pass a linker flag through the compiler.
wl=""
change the lines to this:
# How to pass a linker flag through the compiler.
wl="-Wl,"
