0000471: Large Worlds often cause crashing, graphical corruption

Notes
(0001074) Logical2u (manager) 2010-04-05 07:43	Related to 0000217, 0000216, 0000046, 0000006 - when you say "Graphical Corruption" I assume you mean you're playing with Graphics on? I mean, the game is normally just text, so...

(0001077) janglur (reporter) 2010-04-05 07:52	No, I mean as in 'the default tileset becomes corrupted, with broken images similar multicolored square, garbled text, after images, etc.' in places there clearly should be none within the dwarf fortress screen.

As logic points out, there's several tickets on the subject. You're the first I think I've seen that's mentioned screen corruption when it happens however. I'm not sure what that might mean here. It could simply be another symptom of your hardware under extreme duress from all the memory allocated in the worldgen process. Hardware does some funny stuff when it gets stressed.

(It regularly finds problems games don't.) So i'm very hard pressed to beleive mine AND another different PC are both experiencing the same problem due to identical forms of hardware failure. After some research, I DO see that DF can sometimes exceed the 2GB barrier. If it is a program that can run on Win95/98, then chances are it is limited to a 2GB address barrier, and is causing an overflow/memory corruption of some sort when it breaks said 2GB barrier (AFAIK, any program that even says it can address more than 2,147,483,647 bytes will immediately crash on 9x systems) Very probable considering DF does not in any past version or even on a massive 16x16 map use more than 500 MB normally, only during this wierd worldgen bug.

My custom 256X256 LARGE COASTLINE Freezes up every-time I run it. The raws are modded in my copy, that could have something to do with it, but since it only happens in one parameter set I don't think so. I put up the folder on DFFD ....here ->http://dffd.wimbli.com/file.php?id=2063 [^]
