0000966: Crash occurs at the end of the battle.

Notes
(0002531) James van Bhradok (reporter) 2012-05-23 17:05	For some reason I can not edit my post, so I posted here. While wins in the battle, Crash message pops up as shown in the picture send. This does not occur when you lose.

(0002533) majaczek (reporter) 2012-05-23 17:38	I confirm. It occured to me after 7-th battle for me on vcmi0.88b

(0002538) Ivan (developer) 2012-05-24 15:20	Most probably related to 0000948 I have good news and bad news. Good news: your backtrace looks OK. I think I know what's wrong and how to fix that. Bad news: this is not crash from this bug. What you see is: 1) For some reason client decided to close (actual bug) 2) Client send closing signal to server and disconnected. 3) Server received signal but crashed on closing (this is what you backtrace shows)

(0002543) Tow (developer) 2012-05-24 18:41	If it's reproducible, please provide steps allowing us to reproduce the issue. @James van Bhradok Please don't upload images in BMP format, it wastes both server space and our bandwidths. If you care about quality loss from JPG (though it's usually not an issue), there's always PNG that provides lossless compression.

(0002544) douggie_m (reporter) 2012-05-24 18:47	> I have good news and bad news. There's only news, they are not good or bad, they are just news ;) > I think I know what's wrong and how to fix that. Cool.

(0002546) douggie_m (reporter) 2012-05-24 20:24	Tow> please provide steps allowing us to reproduce the issue Well, it is very reproducible. I got it on ``All for one.h3m'' almost every time. If you can't get "crash on the end of battle", then try to recruit a new hero in tavern and try again.

(0002548) Ivan (developer) 2012-05-25 11:52	Both crashes should be fixed in rev 2709. Please recheck.

(0002559) douggie_m (reporter) 2012-05-25 19:03 edited on: 2012-05-25 19:22	Haven't seen any crashes on the end of battle with rev2711. UPD: Well, the new type of crash appeared, SIGABRT at the time of AI's turn: Time of looking for new exploration point was 660 ms. Time of Evaluating exploration possibilities was 660 ms. Time of looking for best exploration neighbour was 0 ms. Looking for an another place for exploration... Time of looking for new exploration point was 680 ms. Time of Evaluating exploration possibilities was 700 ms. Attempting realizing goal with code EXPLORE vcmiclient: VCAI.cpp:1719: void VCAI::tryRealize(CGoal): Assertion `0' failed. Aborted But this is an another issue.

(0002563) Ivan (developer) 2012-05-25 19:48	Resolved then.
