* The path can be described in 3 "chunks":
* 1. One path from the allocation to the construction of the invalid pointer
* 2. Another path from the construction of the invalid pointer to the final pointer that's about to be dereferenced.
* 3. Finally, there's a single step from the dataflow node that represents the final pointer to the dereference.
* 3. Finally, a single step from the dataflow node that represents the final pointer to the dereference.

* Step 1 happens when the flow state is `TInitial`, and step 2 and 3 happens when the flow state is `TPointerArith(pai)`
* where the pointer-arithmetic instruction `pai` tracks the instruction that generated the out-of-bounds pointer. This
