Kent,

> Any news about this issue?

I had closed the issue after I had sent you the attached response last 
September,
indicating I couldn't duplicate the symptoms.  I have just tried again, and 
still
can't duplicate the symptoms on my Linux Fedora 14 desktop platform, but I
can duplicate the problem on OSX 10.9.  This is strange, because I don't see why
the bug would be platform specific.  Did you only see the original problem on
OSX?

OK, I got it, thanks.

I can't duplicate the error with any of the versions of nccopy I
have built, including 4.3.0, 4.2.1.1, or 4.1.3. In each case, nccopy
completes with no error message, and the size of the resulting output
file is as expected, for example:

$ NCDIR=/machine/russ/installs/nc430 ; ${NCDIR}/bin/nccopy -k 4 -d 1 GLAH.nc 
GLAH.nc4 ; ls -l GLAH.nc GLAH.nc4
-rw-rw-r-- 1 russ ustaff 225935448 Sep 17 13:36 GLAH.nc
-rw-rw-r-- 1 russ ustaff 36385878 Sep 17 14:00 GLAH.nc4

Is it possible the error message only appears when built with some
non-default configure flag, that the version of nccopy you are
using is older (unfortunately it doesn't have a --version flag), 
or that the error only occurs when built with a newer version of 
HDF5 than 1.8.11?
