0009888: Wear-related crash when triggerring a weapon trap

Notes
(0035623) Loci (manager) 2016-07-13 19:57	Please upload a save which consistently crashes to http://dffd.bay12games.com/ [^] for testing and verification.

(0035635) Warlock (reporter) 2016-07-15 15:00	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.

(0035660) HansBr (reporter) 2016-07-19 07:58	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. http://dffd.bay12games.com/file.php?id=12278 [^]

(0035675) Loci (manager) 2016-07-22 21:01	The new weapon-wear code may be destroying a weapon unsafely mid-attack.

(0035812) Christes (reporter) 2016-08-26 11:22	Here's another save, if it helps: http://dffd.bay12games.com/file.php?id=12384 [^] (43.05)

(0035814) Coledash (reporter) 2016-08-27 05:40 edited on: 2016-08-27 05:40	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.

(0035843) thraxarious (reporter) 2016-09-03 18:19 edited on: 2016-09-03 18:20	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...

(0035845) ejtttje (reporter) 2016-09-06 17:45	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?

(0035951) emodwarf (reporter) 2016-10-06 12:31	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: http://dffd.bay12games.com/file.php?id=12486 [^]

(0035983) sapphon (reporter) 2016-10-18 18:43	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: http://dffd.bay12games.com/file.php?id=12510 [^]

(0036048) rmillet42 (reporter) 2016-11-13 07:55	I think I have the same issue (df 43.05 linux64). Here are the gamelog printed at the moment of the crash: The (�iron short sword�) strikes the goblin lasher in the lower body, but the attack is deflected by the goblin lasher's ({�iron breastplate�})! The goblin lasher bats The spinning (copper battle axe) aside with the ({copper whip})! The (-copper battle axe-) strikes the goblin lasher in the left lower arm, bruising the fat through the ({pond grabber leather cloak})! The force pulls the left elbow and the part splits in gore! A ligament has been torn and a tendon has been torn! The goblin lasher jumps away from The spinning (�bronze spear�)! The (+bronze mace+) strikes the goblin lasher in the upper body, bruising the muscle and bruising the right lung through the ({pond grabber leather cloak})! The goblin lasher is having trouble breathing! The (steel spear) strikes the goblin lasher in the lower body, but the attack is deflected by the goblin lasher's x({�iron breastplate�})x! The (steel battle axe) strikes the goblin lasher in the left upper leg and the injured part is smashed into the body, an unrecognizable mass! An artery has been opened by the attack! The force bends the left hip, tearing apart the muscle and bruising the bone and tearing apart the muscle and bruising the bone! A ligament has been torn and a tendon has been torn! The (menacing iron spike) strikes the goblin lasher in the upper body, bruising the muscle and shattering the left true ribs through the x({pond grabber leather cloak})x!

(0036124) Morten (reporter) 2017-01-02 05:35 edited on: 2017-01-04 13:05	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.
