Anyway, I repaired it as follows: 1. Created NC4_write_provenance as parallel to NC4_read_provenance 2. Modified hdf5file.c to use NC4_write_provenance 3. Modified hdf5open.c to use NC4_read_provenance (was NC4_read_ncproperties). 4. The creation of the _NCProperties string was seriously hosed: was using all the wrong fields.
