My game crashed also when a goblin triggered a trap. See: http://dffd.bay12games.com/file.php?id=12264 [^] .Game will crash within 30 seconds. Tested in 0.43.04 and 0.43.05. Platform: Windows 10, Ironhand graphics.

An other example for this bug in Linux, game created in .43.04, replicated in .43.05. this is a save from 43.05

Trolls trigger traps just fine. Sometimes goblins also trigger traps without crash. Until one goblin/trap triggers the crash, not long after this save starts.

The new weapon-wear code may be destroying a weapon unsafely mid-attack.

v0.43.05
I killed 2 Forgotten Beasts with same set of 4 upright spear/spike trap, each trap built from 10 menacing spikes made from iron, no crashes. I tried defending from goblin invasion with large serrated disc traps made from glass, but only 1-3 goblins die before a crash happens reliably. When I inspected the traps just before the crash, the weapons started to be worn down. I then built a trap with already worn down weapons and every single goblin that triggered the trap caused a crash reliably.

The weapon wear is on the traps? Yowch. Might be a problem for some of my trap designs if the weapons cannot be replaced without removing mechanisms. I have a spike pit that is linked to my water cistern, and a repeater. Having to redo 20 rows of 10 spikes each, all linked into a pressure plate connected to floodgates and a kill switch to turn the pit active...

I'm seeing this as well :(
I've uploaded my save: http://dffd.bay12games.com/file.php?id=12434 [^]
Doesn't always crash on the same troll, but always before 3 or 4 have entered the traps.

If this is related to weapon wear in the trap, can we disable that in a settings file somewhere until the bug is fixed?

I'm also having this problem.

Windows 7 Pro 64-bit
DF 0.43.05 (Windows SDL 64-bit)
- using same version from world gen to embark to this save
- vanilla; no mods; no external tools

This is an archived save game of a situation where the game will crash once the
invading force during a siege will reach and start triggering the many weapon traps placed in their path:

Have encountered what I believe to be this issue as well. Weapon traps with wooden spiked balls (4 per) versus gobbos this time.

Save is here, crashes very soon after load:

Another save that reproduces the crash: http://dffd.bay12games.com/file.php?id=12638 [^] This one uses 10 copper serrated discs in each trap.

I agree with one of the above posters that the bug might be related to trap components being worn out, since there isn't always a crash the first time a trap is triggered.

EDIT: Giving goblins the [TRAPAVOID] tag in the raws fixes the crash. As an added benefit, this will cause lots of fun since my fortress' main line of defence is now useless.
