unexpected replication factor metadata

[Christophe Malek]

Hi Vanh and libECBUFR maintainers,

I was just decoding some TOVS/AMSU-A data using bufr_decoder and got some unexpected {R=0} repetition number values where I would have expected to see {R=1}, {R=2}, etc. because the associated data belongs to the 1st, 2nd, 3rd, repetition respectively.

Here is a sample of the output:

  201000 {R=0}

I would have expected that everything under {R=1} would also be {R=1} up until {R=2} because it belongs to the 1st repetition and so on.

I require this so I can query the bcv->meta metadata field in the code to determine which repetition (and nesting level) I'm current at for any given element in order to maintain this structural information in my intermediate data structures.

I was able to work around this but the subsequent bug I found is critical: 1662216
