I was in Madison at SSEC when I saw this message.  I showed it to one of
the developers who should know the answer, and he said that he thought that
this bug has been fixed in 7.6.

Try using the 7.7 version of grdcopy.k.  I installed 7.7 on windfall
last week, so all you need to do is:

login as 'mcidas'
cd bin
mv grdcopy.k grdcopy.k.bak
cp ~mcadde/bin/grdcopy.k .

Then retry your test.
