It was assuming that for any location M.N, N was always less than the number of breakpoint locations. But if you rebuild the target and rerun multiple times, when the section backing one of the locations is no longer valid, we remove the location, but we don't reuse the ID. So you can have a breakpoint that only has location 1.3. The num_locations check would say that was an invalid location.
