Before I tried to hook the entry in my iat, which obviously leads to various
dumb failures...

the first < 5 bytes

I tried to hook a member varialbe. well shit I mean it kinda has to have a similar name, doesn't it

That's actually an embarassing error...

factorial and loop have 8, respectively 9, bytes of instructions before the
jump backwards. Maybe I'll have to redo them, in the worst case I have to do
useless functions
