Unlike 64tass and Merlin, which allow you to redefine symbols, ACME uses "zones" that provide scope for local variables. This means that, at the point of a local variable table definition, we have to start a new zone and output the full set of active symbols, not just the newly-defined ones. (If you set the "clear previous" flag in the LvTable there's no difference.) We could do a bit better by only outputting the symbols that are actually used within the zone, similar to what we do for global project/platform symbols, but that's a bunch of work for questionable benefit.
