Using ``processLineAgainstMesh`` with building elements can result in Crash 0x00084B86

[PlatinMTA]

Describe the bug

For some reason, using processLineAgainstMesh with an array of buildings will crash the game, but only if the amount of buildings tested is "high". I managed to make it crash with under 25 buildings, but on the test I uploaded I am using 100 buildings just to be sure it works.

This doesn't happen with objects.

Steps to reproduce

1. Download the test resource and run it, you should crash.

Otherwise, run this code

local x, y, z = getElementPosition(localPlayer)

local buildings = {}
for i=1,25 do
	buildings[i] = createBuilding(1337, x, y+2*i, z)
end

setTimer(function()
	local px, py, pz = getElementPosition(localPlayer)
	for i=1,#buildings do
		local building = buildings[i]
		local hit, u, v, texture, frame, wx, wy, wz = processLineAgainstMesh(building, px, py, pz, x, y+2*i, z)
		iprint(i, hit, u, v, texture, frame, wx, wy, wz)
	end
end, 1000, 1)
