Segmentation fault
« on: October 31, 2014, 03:05:03 pm »
OS: Linux, Zorin

When playing, completely randomly, out of the blue, the game crashes, and prints "Segmentation fault".

Great. I can repeat what I just did. Not like I didn't do anything tedious or anything -.-

The next day, it happens again.

I can't really tell you anything more about it, all I know is that it happens rarely, randomly, without warning, and abruptly. And that it is apparently a segmentation fault.

How to fix?

The best way to demonstrate it to him is take a save of 40 year old fortress with 150 dwarves in it on a good sized embark with a volcano that just breached the circus and install it on his gaming rig and watch it bring his rig to its knees.

This is... interesting. I took a look at the game log and the last message in the log said that an outpost liaison and caravan from my parent civ arrived. I did not see that message before the crash, so it the crash could have been related to the arrival of the caravan.

If you have a save that can reliably or semi-reliably lead to the segmentation fault, file a bug on Mantis.

I don't know the first thing about Linux, but just for laughs I looked up "segmentation fault". It's another name for access violation: the program is trying to use memory it doesn't have access to (or that doesn't exist), or it's trying to use it in an invalid way.

My guess is that it's just a software bug that created a bad reference somewhere that the game is trying to read when it generates your caravan, which is something you should put on the bug tracker. But I'm not an expert and I don't use Linux, so somebody may have more useful advice for you.

I'm going to research this bug a little more and then report it on Mantis, thanks. My save apparently does reliably lead to a crash :/
