Happens on non-curvilinear grid too, as I discovered when all the curvilinear files were too big to upload. Seems like an HDF issue. Here is a sample file.

Gah! Nevermind. The problem is a mismatch between which hdf version cdo expects and which is installed.

FYI. The required cygwin64 hdf version is libhdf5hl_100 1.10.2-1
