Finally found this thread. Dunno if this makes any sense but I'll post in anyway. Could this crash be caused by enhanced DEP protection? I have DEP enabled to all running programs. It's not default setting.

99% of time everything works ok. Only cracks, keygens etc. And some old games like gta3, gta vc doesn't work with DEP enabled that way. When I had my PC running I also noticed other games crashes (really rarely) with 0xC0000005 error too. Maybe just DEP is to sensitive and detects some functions in games codes wrongly. Coming back to SS. This crash happened few times same/similar and probably it has something to vote, picking up sniper rifle or/and killing players or and joining players, everything same time so it's pretty much impossible to reproduce.
Let's forget about it:D I posted cuz dunno how DEP really works and also I don't like unsolved threads, bum da ts. DEP shouldn't matter. It means 'Data Execution Prevention', and as such, it would trigger on self-modifying code, which we don't do. On the other hand, it can be caused by a bug that causes the code to mixup addresses and jump to a data address. Could happen when a virtual function table pointer for an object gets accidentally overwritten. So, it could very well be that there's rare a bug that would normally cause a crash, but in some cases causes DEP to trigger, which would be hard to decode from our crash dumps.
