Bug#1015282: crashes on some heroes interaction

[cacatoes at tuxfamily.org]

Package: vcmi
Version: 0.99+dfsg+git20220621.54fab9f0-2

Hello !

I'm running the current vcmi version from bookworm.

I started a campaign, played it this afternoon with no trouble.
I made a break.
I resumed the saved campaign game. Now, the game crashes when I try to 
attack the vampires group located north west of the first hero in 
attached savegame.
On that same savegame, it also sometimes crashes simply when moving 
heroes around the map.

Please find attached game logs (I don't know if they contain valuable 
infos) and the savegame.
The game exits. I'm unsure how I can debug this with gdb, if required (I 
tried, it produced no log, maybe it didn't catch the right thread 
backtrace).

Thanks,
