The fixture's loop iterated `[6, 7] as (number | undefined)[]` so that its binding kept the union layout the LLDB check reads through `item->tag` and `item->slot.arm0`. Since (T | undefined)[] stores T elements, an array that never holds undefined gives a `number` binding, and the check failed with "item is not a pointer". The loop now iterates `[6, 7, undefined]`, whose binding needs the union, and the check also reads the undefined arm's tag.
