I found a tag propagation bug in pack_k_bits_bb. Example python file to demonstrate the bug is below. This block takes every 2 bits and packs them into one output. Thus, a tag on input 0 should come out on output 0, and tag on input 7 should come out on output 3. However, as can be seen from this example, the second tag comes out on output 4. This is probably due to the way sync_decimator does tag propagation: round(input_index / decimation). However, that is NOT the correct approach for this block.
It would be useful to report this as an issue on our Github tracker.
