[netCDF #FFY-177157]: NetCDF-4 and 64 bit dimensions

If I understand your question, the answer for the start array is the
same as for the count array.  As an array of size_t values, it is either
32 bits of 64 bits, depending on the platform it's compiled on.  But the
netCDF-3 format only allows 32-bit dimensions on either kind of platform,
because that's all there is space for in the format.

I wish the error message you got was always informative enough to give
useful guidance, but in the case of specifying a start index that's too
large, all the user gets is:

  NetCDF: Index exceeds dimension bound
