DEP Malfunction
« on: March 07, 2010, 06:13:20 pm »
Running an outdated version of DF v0.28.181.40d, and I am getting numerous crashes on my one Fortress.  My PC is telling my that DEP (Data Execution Prevention) is closing the program.  As a side note, the program is quitting after recieving "'Random dwarf' cancels 'random construction task'" messages.

First, do the new versions fix this while retaining backwards save compatability?  I could turn off the DEP feature, but if something is triggering the kill-switch do I have anything to fear?  I guess my question is, can non-malicious but buggy/sloppy/whatever coding screw up my computer?

DEP likes to take credit for random crashes that are inexplicable otherwise.

Thanks for the insight on this DEP, I never heard of it before today.  I have gotten 1 season past where I was getting repetitive crashes, so I think I am in the clear *fingers crossed*

I suppose I should clarify a bit more...

There are any number of possible explanations for the crashes.
I honestly don't know what to tell you if you're running a vanilla copy of 40d, as it's generally fairly stable..  Mods with duplicate entries will cause massive weirdness that has been detailed numerous times before, including the infamous wizard fortress, cave crocodile civilizations, etc., and other nastiness.  What most of those details DON'T tell you is that the game will quite commonly crash with no errors under those circumstances.

DEP will take credit for a crash that is cause-unknown such as those.
For instance, I've had it take credit for a crash of one of the core executables of Windows XP before.  It wasn't fun to try and figure out the reason behind that one, as Windows does not generally kill Windows.

Yeah, I previously had the game crash directly after job cancelation messages.  Windows attributed it to DEP.  I have reloaded and gotten past the season where the crashes occured and have not had trouble since.  Unfortunately that means I can not replicate the error.

I am running vanilla 40d on Windows Vista (x64)
