Summary0001331: KAIK causes a crash after an indeterminate period of time.
DescriptionStarting a single player game or a multiplayer with KAIK included more often than not causes a crash. It is usually after about 30 minutes. I have recreated this by playing a 10x speed game with the GlobalAI Test script. If I let the bot kill me and watch it for a while it will also crash.

I have had this issue for a period of time, but only know managed to figure out meaningful debug information (see included backtraces).

System Details:

Gentoo Linux:
Portage 2.1.6.7 (default/linux/x86/2008.0, gcc-4.3.3, glibc-2.9_p20081201-r1, 2.6.28-gentoo i686)
CPU: Intel Q660
RAM: 2GB
GFX: Nvidia 9600GT (1GB) - Driver version: 180.27

if this problem only occurs on your system, please give info about your system, and get yourself a debug build of spring, and compile with DEBUG3 (if you use under CMake), and debug again.
This way, you get the line numbers in the source files, in the debugger.

If the problem is reproducable, please list describe what we should do to make it appear (eg, mod and map you used to test)

Just a quick update. I managed to avoid this crash if I comment out line 101 in 'UnitHandler.cpp' of KAIK. I'm not totally sure if that's useful, but I am going to get a proper debug going in the next couple of days.

My crashes were mostly on 'MetalHeck v2' with various versions of BA. I am also compiling this with the latest GCC in Gentoo's testing repository (4.3.x).

 bbw: thanks for your continued efforts. I did look into this when you first reported it in my thread (back in november) but didn't get anywhere at the time; catching the crash live would certainly help.

Found the (probable) cause of this thing a few hours ago. If you could grab a checkout of git master to confirm that it's fixed, I'll buy you a beer. ;)

Kloot I have managed to check out the git master. I then merged your fix into the 0.78.2.1 branch and it appears to have fixed the crash bug, so thanks very much. Also I noticed your update in the forum thread and have ported those latest changes to my local copy so I can keep sync with other 0.78.2.1 and use KAIK.

Again, cheers for fixing this :)

If you want me to do any other testing just say the word.
