[gdal-dev] hdf5dataset.cpp patch

[David Burken]

  Hi Everyone,

gdalinfo was core dumping in method HDF5AttrIterate on some hdf5 data we 
have.  The value of nAttrSize was greater than the hard coded array 
length of 8192.  I changed the array size to be dynamic and it seems to 
be working now on my small sample of two data sets.

svn diff below.  I can send whole file if someone would like it but did 
not want to do that to the list.

Take care,
Dave
