> While reviewing some code I realized that there is no bounds checking on
> ArrowBuf slicing. Example negative test case that should pass but is
> currently failing can be found here:
> [https://gist.github.com/jacques-n/737c26b7016ed29dc710d4aba617340e]
> It may be that this doesn't cause more problems because the index checks do
> exist on memory access but fixing this would make it much easier to
> understand where a code mistake was made.
