Subject: NCZ_def_var_chunking(): make sure 'cs' is set before used
Patch-mainline: Not yet
Git-repo: https://github.com/Unidata/netcdf-c
Git-commit: 47584171d90e03b9ddad94cbc7edf1ab20f9d468
References: 

'cs' was only set when 'var->ndim' != 0. Thus cs could have been
uninitialized when ncz_dev_var_extra() was called.
