Linux freezes logs (for the DEVS)

[facePlanted]

Hi so I've collected some game logs, on Linux, capturing when the game crashes.
It happens 100% of the times during night, multiple times, freeze or crash.
While during the day it's 100% stable.

Here are the files:

https://file.io/IOvzS0
https://file.io/ZztIbF
https://file.io/Y3Ey2P
https://file.io/C4OCtr

they are very similar and all end with something like:

Receiving unhandled NULL exception
#0  0x007f7785fdd680 in _L_unlock_13
#1  0x007f7785fddc40 in operator delete(void*)
#2  0x007f7785fddcd0 in operator delete(void*)
#3  0x007f7785fddcf0 in operator delete(void*)
#4  0x007f7785fddde0 in operator delete(void*)
#5  0x007f7785fddeb0 in operator delete(void*)
#6  0x007f7785fddec0 in operator delete(void*)
#7  0x007f7785fddee0 in start_thread
#8  0x007f7785fddf80 in clone

I'm using Debian 8 with gnome-shell, cpu i5-4690K gpu gtx980 16gb of ram (all applications closed except Rust and Steam)

hope this helps, let me know if you need more info
