The GEP instruction seems to be accessing the 18th integer of the structure's array of ints. However, this is actually an illegal GEP instruction. It won't compile. The reason is that the -pointer in the structure <i>must</i> be dereferenced in order to index into the +pointer in the structure *must* be dereferenced in order to index into the array of 40 ints.
