This files in cases where the current working directory does not support writes, e.g., as seen here ``` def test_88_character_filename_segmentation_fault(self): # should be fixed in netcdf4 v1.3.1 with mock.patch('netCDF4.version', '1.2.4'): with warnings.catch_warnings(): message = ('A segmentation fault may occur when the ' 'file path has exactly 88 characters') warnings.filterwarnings('error', message) with pytest.raises(Warning): # Need to construct 88 character filepath

              xr.Dataset().to_netcdf('a' * (88 - len(os.getcwd()) - 1))
