I'd be interested in whether ncks linked against 3.6.0-beta6 returned a write error or simply wrote the file with no indication that anything was amiss. The latter is possible with netCDF-3.5.1 and earlier because of undetected integer overflows with large file system offsets within the library, but with the beta software I would expect an error if ncks tried to create a classic file that violated format constraints or at least an assertion failure from the library. If ncks appeared to work fine with no indication of any error, I would consider that a bug in netCDF-3.6.0-beta6 that we need to investigate further. --Russ
