The same problem I encountered under Debian Wheezy. If you require I can upload the saved game status.

There are two other but very similar tickets 0001839 and 0001840 reporting this bug.

Is it new in version 0.96?

amergl, upload saves and logs so we can make sure that this is the same bug.

Logs are usually in ~/.cache/vcmi/ directory, saves are in ~/.local/share/vcmi/Saves

Thanks. Yes, looks to be at least similar. All 3 issues have a crash during AI turn so I've marked them as related.

Most likely same issue on Ubuntu 14.04. Console output:

Our heroes don't move anymore, exhaustive decomposition failed
[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.

Save game attached (savegame.zip)

Same issue here. Ubuntu 14.04 also. Kind of annoying, since I just discovered this, and now I can't play past a few turns :(

Can provide saved game / more logs if necessary, very easy to reproduce (it's happened to me on 2 different games, after a week or so).

Where it says "SNIP" there are about 70 copies omitted of the allied hero error.
Maybe some sort of infinite recursion for pathfinding..?

Full terminal output:

It happens in almost every game. It's very annoying.

Saves are very old and impossible to check. The AI has been improved during this time and I believe this ticket is no longer relevant.
