 Still nothing...
There may be some specific action you've done on last turn that leads to crash.
Can you reproduce this crash by loading last valid autosave and repeating this turn again?

 now even if i start a new game i get the above. Does the game save a state to a temp file that i can delete or something?

2011-07-23 20:37

 nevermind, it seems the server was still running in background even if i killed the client. now i can load the previous save and start new game

 loaded privious save and tried all actions now it doesn't crash, i really don't like random things :(
(0001872)
Ivan (developer)
2011-07-23 21:30

 Yeah... Random bugs are really annoying.
I'll try to play this map. How often these crashes happens?
(0001873)
lssjbrolli (reporter)

 It happens on other maps too, first crash was about 1month and a half.

 No crashes after one month of gameplay. Will try to play a bit longer this time.

What versions of g++ and boost you have?
(0001876)
lssjbrolli (reporter)
2011-07-24 18:44

 gcc is 4.6.1 and boost 1.46.1

 Does the server at the moment of crash create a savegame file (*.vlgm1)? If it's not empty, please upload it. Also, what's in the VCMI_Server_log.txt after crash?
Is there any specific pattern when does bug occur? (Eg. just after new month)
(0001878)
lssjbrolli (reporter)
2011-07-25 12:44

 yes i will upload save and log. There is no pattern, now even if i didn't do anything just end day it still crash.

 first crash in 3,4,4 to 3,4,5 (month, week, day), if i load previous save and end day it does not crash. second crash 5,4,6 to 5,4,7.

 Thank you for further information. The windows crash issue is 0000759 I guess.

As for the Linux one... it is not related to autosave, the save file looks fine, VCMI crashes after it's already written.

On the other hand, logfiles suggest that crash occurred when turn 85 was starting... that's start a new week, as confirm entries about setting heroes available in taverns and their initial armies. Moreover, it's also start of the new month (turn 85 should be month 3 day 1)... I'd say it's still something in new month or new week handling code. However you say that game also crashes in the middle of week.
Could you also provide us with a logs when such case occurs?

 sorry for delay, damn work :(, i've uploaded the logs.

 it seems you were right and it is related to 0000759

 i saved on 1,4,7 and reloaded until it crashed.

 I believe it's the same issue as 0000848, that was fixed in r2549.
