Arma 3 was crashing on me randomly, this is a crash to desktop. It just happened to me when I had alt-tabbed out of the game and then tabbed back in.
I am not sure of the actual problem, this is an access violation error.
I have uploaded the crash dump files here: http://www.securitronlinux.com/arma3/ArmaReport_Log_20170930T192041_CorporalXKerry.zip
This was mostly happening repeatedly when I was trying to connect to a Invade and Annex server, but I tried a Domination RHS server and it was fine.
Looks like steam overlay crash.

I fixed it by deleting the GameOverlayRenderer64.dll in the Steam folder, then creating an empty file with same name and making it read-only. That fixed this crash for me. This ticket is resolved.
