This also seems to happen fairly reliably with the vanilla world generation (large maps) so far.

I'm going to go ahead and mark this issue as resolved. I am in the process of world-generating with the new patch using the same parameters as I put into this ticket and I'm already at year 850. Also, while memory usage is definitely higher than DF version 0.41, it is well below the 2 GB limit, hovering at slightly under 1.5 GB. I'm attributing this to the new features' overhead. If I run into any new crashes, I'll open up a new ticket.

It is possible it was something else, but thanks for the follow-up.
