[2.0.32] Crash on linux, unreadable stacktrace

[neamar]

Hello amazing devs,

I got my very first Factorio crash.

Most notable thing: I enabled background saving for Linux a couple days ago, which may or may not be related?
Including the save file (it may include more changes that what I had at the time of the crash, not sure if I saved on top of it)
Restarting the game did not trigger a new crash.
Only using Space Age mod.

```
710.029 Error CrashHandler.cpp:643: Received 6

Looking forward to many more hours of gaming!
