I’m not really that familiar with the sanitizers, and I know there are some sanitizer tests that explicitly test what happens if we *do* fall off the end of a function, so I wasn’t sure whether that was relevant here or not; if just returning `nullptr` is an option here then I’ll switch to that instead.
