I don't have time to think about the issue right now, I'll make another post later today.

I keep thinking buffer overflow; and keep hoping it is not. (hence the sentence in my previous post)

Just guessing, but it looks like a lot of variable assignments (“set”) or counters (“tick”). Except for the “[C]…” line, which looks like a looping statement (“foreachi”).

Set is use to set the x,y,z components of a vector.
Tick is called at periodic short intervals to simulate continuous behavior of all things (weapons, ennemies, bullets, effects...) in the game.
foreachi = for each i (I guess i is for item in a array or integer representing a identifier of a instance of a class (a bit like a pointer)).

Correct

It's the call stack, deepest on the first line. The problem is that this call stack dump is INCOMPLETE !! I mean, the game says:
./Data/LScripts/Classes/Types/Vector.lua:53:Set
./Data/LScripts/Classes/CPlayer.lua:1880:Tick
but at CPlayer:1880 there is a call to Current Weapon's Tick function. And ofc Tick happens to be the n°1 longest and most subfunction calling function. Yippee!

Boy, I do love my 1024.
Boy, the devs used 1024.
Boy, don't say "scruffy" until you have tried putting Cfg.GraphicsQuality=0 in config.ini. xD

So I'll assume we have the same

Quite unorthodox for a buffer overflow...

1-haha lol
2-Or you could simply avoid the gew98 and find&use the other rifle (smle). But that would be admitting defeat.

Apparently you seem to have some coding experience, so you can try downloading a tool named "Painfull" by xentax to extract the .pak files. Extract lscripts.pak in data\lscripts and you can strat editting the code with notepad. No need to compile or repack the data. (ie: you can delete lscript.pak once its content is extracted, the game directly reads the extracted content)
