Strange, I can't reproduce it from a new game, but I can from within your savegame... I'll ask around if any other dev is able to reproduce this

comment:4 by 1player, 7 months ago

Mind sharing your save? I tried bisecting the crash, but older versions refuse to load the game as the file has an 'invalid version'. The earliest I've been able to try is v2.8.0, which still segfaults.

By the way, this is the stacktrace:

These work for me, thanks (it crashed three times before I made a save, I didn't want to replay the whole thing again.)

comment:7 by AndywinXp, 7 months ago

Just to be sure: are you able to replicate it each single time? (EDIT: Meaning, playing from the beginning).

@eriktorbjorn did some useful debugging on this ticket and found out that upon loading your save (which crashes on our end as well) _curMusicState was 1090519115 which likely smells like memory corruption...

Also, just to be sure: are you able to replicate it with the same data files on another device?

comment:9 by 1player, 7 months ago

I don't have another device to test with. I have played from the beginning only once AFAIR, and made a few saves along the way. It is possible the corruption started on the first save. I haven't tried replaying the whole thing again on a fresh save.

Oh 🙂 that changes things... It's definitely possible that this was a one-off corruption thing. When you can please try the first 5 minutes of the game on a fresh start (up until you get inside the asteroid) and tell me how it goes.

Any news on this?

Got a mail answer by the original user: "Sorry haven't had the chance to test. I blame a random corruption in my save, so feel free to close the issue."

Thank you for the follow up :-) closing
