Crash with savegame to reproduce

[xzu]

100% producible bug with build-18 under ubuntu 16.04.

Recipe:

1- load attached save game
2- do nothing, just wait about 10s
3- and then then game freez and crash.

I've also send bug report by apport (automatic bug report for ubuntu package).

I have other saved game, if that can help. Some before this one that make the crash, and some other that don't.

Sorry xzu, this bug report was overlooked.

Build 18 is quite old, currently build 19 is the official release of widelands. I guess no one will look into this issue, since the code basis has changed a lot since build 18 and the underlying bug may has already been fixed.

[xzu (xzurukneg)]

The Crash occurs exactly the same with build 19. Please test it.

[kaputtnik (franku)]

I do not have build 19 anymore, sorry, it does not compile on my system.

The current development build, which i use, is incompatible with your savegame :-(

In some weeks a new official release will be released.

You may has to wait until someone using build 19 test your savegame.

Can reproduce. Will look into it…

The problem is that a ware (snack) that is stored in the port at 83/16 believes it is not in a building but still being carried by a worker, and this worker doesn´t know where he currently is. I´ll now try to find out how that could have gotten messed up…

[Benedikt Straub (nordfriese)]

This is already fixed in trunk, see bug 1639444. The ware is being carried while it´s on a ship, causing a segfault.

You can continue playing without the crash if you destroy all ships close to the said port before the snack (it´s near the barrier just southwest of the port when the savegame starts) arrives in the port.

Thanks Benedikt :-)

Fixed, ok good news. Thanks!
