ah, think I'm with you @jh7370 - maybe if we just say "the nearest non-zero previous address within this line table sequence" (line tables have a concept of a sequence - essentially from a set_address operation to an end_sequence operation) - we shouldn't cross into another sequence when doing this sort of thing.
