geo_switch_anim_state()

s32 geo_switch_anim_state	(	s32	run,

Bug:

Every geo function declares the 3 parameters of run, node, and the matrix array.

This one (see also geo_switch_area) doesn't. When executed, the node function executor passes the 3rd argument to a function that doesn't declare it. This is undefined behavior, but harmless in practice due to the o32 calling convention.
