0009243: Segmentation fault (core dumped)
On world generation, I get a core dump about 1 or 2 hours into world generation (at around roughly year 500). Possible memory leak maybe?
Launch Dwarf Fortress, create custom world with the following parameters (refer to Additional Information)

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.
