Looking at your log spookster it does look like you're running out of ram. it says its only using 74% of RAM but you got 4gb of ram which multiwinia (which is 32 bit) can't completely use so it is actually at its max.
Both of our stackstraces seem to have a sound path in it so it's likely to be a sound problem, but considering we both have different sound cards and different OSes and it doesnt seem to be a problem everyone is getting i dont know anything that the both of us have.
You seem to have an ATI card and the same drivers as me so that could be the cause, but i dont see how that is related to the sound.
It's possible the latest ATI drivers have a bug in the OpenGL code that is sucking up the memory, and the code crashes in some sound related section because it tries to allocate more memory there (but even then a lot of ATI users should be reporting this.., im just wildy guessing here)
It's up to the IV team to either fix it or give us clues on how to do it or what's causing it because i'm running out of ideas..
Does it crash for you if you start a match and leave it open for an hour or so? because it does for me.
