[netCDF #MRV-404062]: File can be read by ToolsUI but crashes ncdump (?)

Hello Matt,

I've started to investigate this and, at a glance, it appears to be an issue 
with the hdf5 library netcdf uses for netcdf-4 files.  I say this based on the 
following stack trace:

#0  0x00000001031ea430 in H5FL_arr_malloc ()
#1  0x0000000103299bd2 in H5S_extent_copy ()
#2  0x000000010329970f in H5S_copy ()

#4  0x00000001031b3536 in H5D__read ()
#5  0x00000001031b2fb7 in H5Dread ()
#6  0x00000001000694a4 in nc4_get_vara ()

#10 0x00000001000077da in print_rows ()
#11 0x0000000100007718 in print_rows ()
#12 0x0000000100007222 in vardata ()
#13 0x0000000100004e48 in do_ncdump_rec ()
#14 0x0000000100003acc in main ()

I will continue to investigate, but I was hoping you could tell me what version 
of libhdf5 you are using?  

Thanks, have a great day,
