I wonder why using the netCDF4 python interface works fine with this scenario.  It must not be using the nccopy code.

I will see if I can test a newer netcdf library.  This is definitely an edge case, but thanks for providing a workaround!

The netCDF file is an excerpt from a hydrology water modeling input file.  Definitely a bit of legacy workflows and files involved.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,422903285

I just tried both of these in a minimal example and I still get the same exception.  ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,422903285
