populations quantity wrong offset?

[tsurezuregusa]

I do not know if this is a bug, but the problem in issue #1646 made me think this maybe is also wrong offset or something like that.

In df.global.world.populations there are many with quantity 10000001. This seems strange. Maybe should be 1.

[DFHack]# lua ~df.global.world.populations[0]
<local_population: 0x170c973d0>
type                     = 7
race                     = 4
plant                    = 4
quantity                 = 10000001
quantity2                = 10000001
flags                    = <local_population.T_flags: 0x170c973dc>
population               = <world_population_ref: 0x170c973e0>
wp_unk_10                = -1
wp_unk_18                = -1
wp_unk_1c                = -1
unk_v47_1                = -1

IIRC this is a "magic number" that means this population is too numerous to count. Seeing the type/race/plant decoded might give more info. Usually the vermin populations are not counted.

Those populations aren't all animals - you have to look at the "type" field to determine whether you should treat it as a Creature (types 0/1/3/4) or a Plant (types 5/6/7).

[lethosor]

Alignment issues are usually more apparent when looking at the hexadecimal representations of numbers, and 10000001 = 0x00989681, so I wouldn't normally think this was an alignment issue. If all values of quantity(2) started with 0x0098 or something similar, or if we were seeing values like 0x00010002, I would suspect that it could be two int16s (or maybe four int8s) instead of an int32. My understanding is that some values of these fields are in a normal (smaller) range, so the field definition is probably correct here.

[tsurezuregusa]

Yes, I should have thought about hex numbers. Sorry for taking your time.

And I forgot to check for type in test code. It is mostly plants.
