gauss is passed by value, and so var has a copy of it. This means that when you generate values with var, the state of gauss does not change.

Wow, thanks for helping me out there so fast. I completely missed this, and was especially confused because storing rng did work - which, I only now realise, is because that is passed by reference (something I did to share the generator among several variate_generators I suppose). Thanks. I'll sleep more sound now :)
