Created attachment 429334 [details] simutrans debug output I am getting consistent buffer overflow crashes in simutrans. The crashes seem to always occur while I'm actively playing the game. I've let it plug away running the simulation for a day or two with no crashes, but when I sit down to do any kind of updates, it crashes after a couple minutes to a couple hours. For my longest run, I saved the game frequently, which seemed to extend the playing period, but it eventually crashed. I then tried to reload the game, but that crashes with just scrolling the display. Output of --debug 5 is attached. BTW, I noticed that 120.1.3 is out, so maybe there is something in a version bump?

Thank you for the report and the backtrace. To me it looks like a bug in the source (upstream), but not in the ebuild package. I suggest to try the latest version: games-simulation/simutrans-0.120.1.3 is available in gentoo already. Is the bug fixed there? If the bug is still open it could be reported to the simutrans developers. I close the bug here, because I do not see a connection with gentoo. Please give further information, if I am wrong.
