unexpected replication factor metadata

[vsouvan]

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:
012064 TEMPERATURE DE L'INSTRUMENT K MSNG
002151 IDENTIFICATEUR DE RADIOMETRE CODE TABLE 6
012064 TEMPERATURE DE L'INSTRUMENT K MSNG

101015 {R=0}

310012 {R=1}

002150 {R=0} NO DE CANAL INSTRUM. TOVS/ATOVS/AVHRR CODE TABLE 28
025076 {R=0} LOG10 RADIANCE TEMP NBR ONDE CENTRAL ATOVS LOG/M 3.899756
025077 {R=0} COEFF CORRECT 1 BANDE PASSANTE POUR ATOVS NUMERIQUE MSNG
025078 {R=0} COEFF CORRECT 2 BANDE PASSANTE POUR ATOVS NUMERIQUE MSNG
033032 {R=0} MARQUEURS DE QUALITE POUR CANAL ATOVS * MARQUEURS MSNG
201132 {R=0}
202129 {R=0}
012063 {R=0} TEMPERATURE DE BRILLANCE K MSNG
202000 {R=0}
201000 {R=0}

310012 {R=2}

002150 {R=0} NO DE CANAL INSTRUM. TOVS/ATOVS/AVHRR CODE TABLE 29
025076 {R=0} LOG10 RADIANCE TEMP NBR ONDE CENTRAL ATOVS LOG/M 4.020109
025077 {R=0} COEFF CORRECT 1 BANDE PASSANTE POUR ATOVS NUMERIQUE MSNG
025078 {R=0} COEFF CORRECT 2 BANDE PASSANTE POUR ATOVS NUMERIQUE MSNG
033032 {R=0} MARQUEURS DE QUALITE POUR CANAL ATOVS * MARQUEURS MSNG
201132 {R=0}
202129 {R=0}
012063 {R=0} TEMPERATURE DE BRILLANCE K MSNG
202000 {R=0}
201000 {R=0}

310012 {R=3}

002150 {R=0} NO DE CANAL INSTRUM. TOVS/ATOVS/AVHRR CODE TABLE 30
025076 {R=0} LOG10 RADIANCE TEMP NBR ONDE CENTRAL ATOVS LOG/M 4.224747

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
