[netCDF #EKV-496024]: Is there an email list for netcdf?

Hello,

This is interesting, as we don't see this error when using mpich on OSX.  I 
notice you are using openmpi-3.1.3. It is worth mentioning that there are known 
data corruption issues with openmpi 3.1.3 and 4.0 and HDF5 1.10.x, as 
documented here:  
https://portal.hdfgroup.org/display/knowledge/OpenMPI+Build+Issues. 

I've installed 1.10.1 using openmpi on my OSX machine, using openmpi 3.1.3 as 
provided by the 'homebrew' package management system, and am unable to 
duplicate this issue. I built and installed hdf5 using this version of openmpi 
with no immediate ill effect, and building the most recent `master` from github 
wasn't a problem.  You might try building hdf5 from scratch instead of 
installing it with your package manager (I believe you are using macports?).  
If that doesn't solve the problem, or if you'd rather ask on the mailing list, 
you can find information to join the netCDF mailing list here: 
https://www.unidata.ucar.edu/software/netcdf/mailing-lists.html

I hope this helps!
