Summary0002463: Reproducible crash on worldgen
DescriptionAfter generating a world, browsing around it, then aborting and going to create a new world, DF crashes. Happens on medium (129x129) regions at the -very- least. The crash seems to happen between cave civilizations and regular civilizations. Also of note is that it didn't happen with a pocket region.
Steps To Reproduce1. Create a new "MEDIUM REGION"
2. Start a new game in Dwarf Mode
3. Browse across the entire map - pattern doesn't appear to matter, but getting all around the map does seem to matter.
4. Escape out, abort game
5. Create a new "MEDIUM REGION"
6. Crash before civ placement
Additional InformationGoing all around the map -is- important to reproducing the bug. The pattern doesn't seem to matter, but I have a habit of looking all over the map for that "perfect embark spot" - and I quit out when I can't find it, formerly by closing the process. Since it happens with a medium region and not with a pocket region, I'd -guess- that it's a memory problem of some sort. :p

Also of note is that it seems to work with an old region after a fresh start. You should be able to reproduce this yourself with any old medium region you've got hanging around.

Edit: Related to 0002432 - I've made that issue reproducible though. :D

Happens to me as well. Just made a large world, messed up a parameter and aborted to fix it. Crashed when making the second world got down to placing civilizations at about 14 (started at 50) and crashed out. Had it happen quite a few times already. Never had it crash on the first world generation after starting DF. Only if a previous world had been generated without closing/re-opening DF.

What is your memory usage just prior to the crashes? And are you running a 32bit/x86 OS, and with how much memory?

I'm imagining this is just the "memory leak after world gen" bug that was previously reported.

32 bit OS, 3GB ram useable - but the memory usage didn't get over about 122MB on the task manager.

After some poking around, I'm assuming you're talking about issues 0000217 and 0000046. I'd believe it's the same issue, except that I generated a new world, searched around, and finally embarked on a 16x16 area with no issues (other than the thing being bloody slow) and no crashes.

If it were a memory leak, I'd think that it would be a bit more random than "reliably crashes after running the steps, and in the same spot each time" :D

Updating my info on this. I've been working with a small (62x62) region, and it will cause a crash with the steps if I browse the map from one end to the other - not even going up and down the map, just across it once.

Reminder sent to: epsilon

Did these crashes leave anything in your errorlog, e.g. "Impoverished Word Selector"?

Good question. I'll actually download .10 and recheck the whole mess. It was easy and reliable enough to reproduce the first time. I'll edit with an update within the hour.

Edit: Your update, sir.

Since I'm not entirely ready to play .10 yet, I ran the game straight from the "small" download - no music or sounds or whatever are included, but I didn't touch any of the init files either.

The result? Not a peep out of the error log. That is to say, the file wasn't generated at all. So no, no messages out of errorlog.txt

Edit of the edit: [^]

Looks like this has popped up before, minimal though the information may be.

Third edit:
I'm assuming that y'all, like most sane people, are asleep anyway and won't notice three edits. :P

A little quote from the DF2010 string dump at [^] :
*** Error(s) finalizing the symbol
Unrecognized word token:
*** Error(s) finalizing the translation
Impoverished Word Selector
Machine node out of bounds on split
Failed to find machine node frontier on split
Unreachable machine node on split"

If I had to guess, (and mind you, this is a VERY wild guess,) the "Impoverished Word Selector" error would seem to be linked to the choosing of names - for civilizations, dwarves, structures, etc. Assuming the info in the string dump hasn't been sorted in any way, it stands to reason that the last bits of the section with the error in it would be a part of the error check/sanity check routines in worldgen. Perhaps a better question would be, has it come up in places other than crashy worldgen, as implied by the post above?

Still happens in .12.

Also, I'm not getting any error about impovershed word selector with the crash. I am using the language files that come with Maydays Graphic pack, so that mught have something to do with the error not appearing.
