[Freeciv-Dev] (PR#10977) autosettlers or unit roles bug

["Mateusz Stefek" <mstefek@xxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=10977 >

Last thing I remember before pressing turn done was that I manually
moved a settler from caravel. I was in AI mode

Can't reproduce, but the server was run via gdb that time
gdb:

Program received signal SIGSEGV, Segmentation fault.
0x080b471f in base_city_map_to_map (city_tile=0x0, city_map_x=2,
city_map_y=2)
    at city.c:107
107       x = city_tile->x + city_map_x - CITY_MAP_SIZE / 2;
