Hi Heiko,

Thanks for sending the bug report.  I've created a Jira issue
describing the bug:

  https://www.unidata.ucar.edu/jira/browse/NCF-141

A temporary workaround is to avoid having a dimension with the same
name as a variable, when the variable is not a coordinate variable for
the dimension, as is the case with the unused "time" dimension in your
file and the "int time(yc,xc)" variable.  I've verified that the
compression works OK if either the dimension or variable is renamed,
or if the unused dimension is deleted.

I'm not sure whether this will get fixed before the 4.2 release, as
the bug appears to occur because code is missing to detect this case,
and it may need to be added in several places in the netCDF-4 library.
