Details:
Split out from bug #17459, where roywephy originally reported it:
Trunk and S2_3 (r18960), and reportedly trunk r18867, give lots of errors and
crash when loading savegames created from the bundled
british-isles-85x80-v2.80 (73x81) and europe-200x100-v2 (177x100) scenarios.
roywephy suggests <https://gna.org/bugs/?17459#comment2> that this is
correlated with an odd width (and/or possibly height). I notice that I not
allowed to manually set odd width or height via xsize/ysize server settings
("The map width must be an even value"), but I don't know why that is.
If the map width/height is required to be even for some reason, do we need to
tweak the bundled scenarios, and possibly add assertions/errors on scenario
and savefile load to catch odd widths/heights? Are there any valid
savegames/scenarios that we'd refuse to load as a result? (I note that the
relevant scenarios have the same proportions on S2_2, so the answer is
probably yes.)
Here are the errors and backtrace I get for S2_3 r18958 on the attached
europe.sav.bz2.
