Oh, and I think I had Population cap at 100, but I doubt that's the problem.

Using a vanilla Dwarf Fortress 0.31.25 SDL installation on Windows 7 64-bit, I embarked in that exact region (using "Play Now!") and it worked just fine - only 252MB of memory in use.

Do you still experience this problem if you load the save in vanilla DF with no third-party utilities? You can download vanilla DF at http://bay12games.com/dwarves/ [^]

Odd.
I just tried 2x3 and 2x2 sizes. They didn't crash, but ended up at 1.5GB and 1.5GB use respectively.
However after the introductory text when I press enter I just get a black screen and the game is not responding.
Once I got the graphics drawn but the game was frozen. Moving windows around didn't refresh the graphics on the game window. Music kept playing though.

Also, I just tried a 4x4 area in two other parts of the map. No problems.

I have only ever used Lazy Newb Pack btw.

Will try vanilla SDL.

Yes. Crashed in Vanilla DF SDL with music.
Same 3x3 area.

And crashed in Legacy DF with music. Same 3x3 area.

BUT: Didn't crash in Legacy DF without music. Same 3x3 area.
The memory use stopped at about 1943MB (edit: fixed typo) and I got the intro text.
But, like before, the game was not responding after pressing enter.

Still, I'd say it's pretty much "crashing" :)

Have you tried updating your audio drivers? Enabling music shouldn't cause the game to use gigabytes more memory.

Heh, sorry that was a typo. I meant it used 1943MB :P , or 1.943GB ..
So just under 2GB, hence not crashing but still strange.
Did anyone else manage to reproduce it? It's really weird that I should manage to crash it but Quietust doesn't.
I also tried embarking on areas (3x3) covering only either of the 2 biomes in the screenshot area.
Still crashed. There's something about that place.

I didn't manage to embark there, and didn't even get to the "You have arrived" speech.
You can export the worldgen info from legends mode and use that to regenerate the world. Does the crash persist in the regenerated world?

I am seeing the same thing with 0.31.25 linux version.
Memory use steadily increases after embark and eventualy after about 5-10 minutes the strike the earth screen is shown. After that only a black screen with a fps counter is shown. The game then apears to lockup as the fps counter does not change.
Final total memory usage was 77.5% of 3.0 GB of Ram or 2380.8 MB and occured after the game appeared to have locked up.

Reminder sent to: Panzerdwarf

Did your high-memory 3x3 embarks have an excessively high number of X-levels? That would point to feature corruption as in 0002713 and 0005077.

Urgh, I haven't played the game much since August last year so I have no detailed memory of the crash. And what's X-levels? :) Sorry...

You're going over the 2 GB memory limit? That would appear to be related to this:
