[Freeciv-Dev] Client core dump unit_list_iterate (PR#1525)

[Christian Knoke <chrisk@xxxxxxxx>]

CVS 31 MAY 2002

I've had a client crash in a special situation:
Just before game end, after I conquered the last
enemy city, before turn done, I saved the game.
Loading the saved game and reconnecting the client crashed it.

It was not reproducible, it seems to depend on the client state.

Backtrace:

While I tried to reproduce it, I got a message at game start (in german):
ASV: [] wird nicht mehr von uns verwaltet, da es uns nicht mehr gehört.
Note, the "[]" represents a square on the screen. There should have been
the city name. Also the message is wrong.

core file available.
