carolina-december-eight crash

[LegendaryMods]

What happened?

If an NPC shoots another NPC the game will crash. This causes other players in the area to crash, if they're nearby.
I've tested this on multiple game builds (b3095, b3258, b3323 & b3407,) and multiple artifacts, and it seems to only happen on b3407.
I've also tested this across multiple servers, including one with a a fresh install of the Default CFX recipe provided by txAdmin.
This happens on both Linux, and Windows servers. CfxCrashDump_2025_01_28_18_16_38.zip

Edit: Shooting armed NPCs will also cause a crash to happen.

I've tried on b3407 being killed +14 times in the same spot with the same NPCs but I can't reproduce the issue. Am I doing something wrong?
Edit: Finally able to reproduce the crash shooting to an armed NPC

[CrazedslawDev]

Ive been consistently getting this issue whenever trying to shoot armed NPCs (specifically altruist cultists or armed bank truck guards as part of a script)

I've been investigating for a while but I still haven't found a solution, in case anyone finds this useful:

Location: 48 8B 81 ? ? ? ? 4C 8B 90 ? ? ? ? 49 8B 82
Function Name: CPedIntelligence::IsThreatenedBy
Instruction Crash: mov     rax, [rcx+358h]
Reason: rcx = 0000000000000, rcx means self of CPedIntelligence
Called from:
	CPedIntelligence::IsPedThreatening:
		Location: 48 ? ? ? ? 57 48 ? ? ? 41 ? ? 45 ? ? 41 ? ? 48 ? ? c6
		Instruction: call    CPedIntelligence__IsThreatenedBy
		Reason: self is invalid
		Called from:
			CTaskSmartFlee::ShouldConsiderPedThreatening:
				Location: 48 89 5C 24 ? 57 48 83 EC ? 48 8B F9 48 8B 89 ? ? ? ? 48 8B DA E8 ? ? ? ? 84 C0 75 ? 32 C0
				Instruction: call    CPedIntelligence__IsPedThreatening
				Reason: Yet I didn't find the exact cause but I only think about the first argument of ShouldConsiderPedThreatening that is a invalid CPed* or that CPed is a valid pointer but miss the m_pPedIntelligence

Maybe my research is wrong but I hope it can help.
