Why does MATLAB 7.0.4 (R14SP2) quit when I am running HDF5 functions on Mac 10.3x?

Whan I executre the following code

if exist('test_hdf5.h5'),

      delete('test_hdf5.h5'); 

end;

! ls -l test*

x = 100 * rand(size(zeros(20, 30)));

gat = 'name1';

gat_details.Name = 'gatt';

gat_details.AttachType = 'group';

gat_details.AttachedTo = '/';

disp('*** build HDF5 file of the volume; start with details only ');

hdf5write('test_hdf5.h5', gat_details, gat)

clear mex

disp('*** finish writing details ');

disp('*** get info ');

hinfo = hdf5info('test_hdf5.h5')

clear mex

x_details.Name = 'x';

x_details.Location = '/';

disp('*** build HDF5 file of the volume; now write data  ');

hdf5write('test_hdf5.h5', x_details, x, 'WriteMode', 'append')

clear mex

disp('*** finish writing data ');

disp('*** get info ');

hinfo = hdf5info('test_hdf5.h5')

clear mex

the ‘get info’ line is displayed and MATLAB hangs up after that. After some time, a dialog opens displaying the following error:

 MATLAB Application has quit unexpectedly

This bug was fixed in MATLAB 7.1 (R14SP3). If you are using a previous version please read the following:

There is a bug in MATLAB 7.0.4 (R14SP2) that shows up when using HDF5 functions on Mac 10.3x. To work around this issue, download the attached version of the Mexmac-files and Dylib-file. Here are the required steps:

1. Quit MATLAB

2. Rename the following Mexmac-files and a Dylib-file:

   $MATLAB/toolbox/matlab/imagesci/private/hdf5readc.mexmac 

   $MATLAB/toolbox/matlab/imagesci/private/hdf5writec.mexmac 

   $MATLAB/toolbox/matlab/imagesci/private/hdf5infoc.mexmac 

   $MATLAB/bin/mac/libhdf5.dylib

(where $MATLAB is the MATLAB root directory on your machine, as returned by typing

matlabroot

at the MATLAB command prompt.)

Rename the Mexmac-files to filename.mexmac.old and Dylib-file to filename.dylib.old.

3. Download the attached files. Place the new Mexmac-files in the directory mentioned in step 2 i.e.

    $MATLAB/toolbox/matlab/imagesci/private/

and place new Dylib-file in the directory as mentioned in step 2 i.e.

    $MATLAB/bin/mac/

4. Change your directory to $MATLAB/bin/mac/. Please create two symbolic links to the Dylib-file by typing the following commands from the Mac terminal application :

     ln -s libhdf5.dylib libhdf5.0.dylib

     ln -s libhdf5.dylib libhdf5.0.0.dylib

4. Restart MATLAB

5. After restarting MATLAB, issue the following command at the MATLAB prompt:

rehash toolboxcache
