[1.0.0] Crash while game paused, garbled stack

[Xenophore]

Started up a new Angel's (minimum Bob's) modded game, played about 25 minutes, got called away and paused the game. Switched to another workspace, did various unrelated tasks. Switched back to the original workspace back about fifteen minutes later to see the crash dialog. I believe it happened before I hit Escape to unpause, but I don't remember exactly.

Cannot seem to reproduce.

Log and last autosave attached.

Thanks for the report. Looking at the stack trace it makes no sense and looks like some memory corruption issue. It goes from constructing a EmptyWidgetStyleSpecification to running a default constructor for a class (OptionalFundamental) to reading from an INI from disk to Character::postCloned(). That's not a valid call stack in any world.

That makes me think you have some memory corruption issue going on with your machine. I recommend running something like this: https://www.memtest.org/

Running memtest overnight a few times didn't reveal any issues. I haven't seen the bug again.

@Rseding91: Another garbled stack, this time in 1.0. I saved, paused the game, and went AFK, coming back to the following:

memtest isn't showing any issues, and the crash only happens while left paused and unattended.

There's no code path that would ever make that series of jumps; that's just full on corrupt everything.

memtest isn't showing any issues, and the crash only happens while left paused and unattended.

Just a guess, but if memory's fine and it only happens when paused and unattended, maybe it's getting pushed to the page file and the hard drive is dying? Does it go away if you disable the page file?

Doesn't seem to be swap related. I'm on Ubuntu 19.10, 16GB RAM, and there isn't any swap pressure. I'll try logging for the next time, but

Code: Select all

cat /proc/$PID/status

shows

Code: Select all

VmSwap: 0kB

even after playing for a while.
