Segmentation fault after loading game.

[Michael Uleysky]

I loading one of my savegames (on map Riverland) and after few seconds game crashes with segmentation fault. I attach this savegame. Widelands build15 compiled from source by script build_and_run.sh. GCC 4.4.2.

[Victor Pelt (victor-pelt)]

gcc 4.4.3 also has this issue. at first glance it crashes when a geologist tries to create a resource marker. will try to fix later today

segfaults on mac too.

[Timowi (timo-wingender)]

I found this bug. It's caused by a gamedata inconsistency. Because amount is higher than max_amount it tries to place a non existing resource indicator.

[Victor Pelt (victor-pelt)]

Michael did you hack the map?

[Michael Uleysky (uleysky)]

Sources, to be exact. I think that amount is any 32-bit signed integer.

So, It was my bug, sorry.
