Drive by comment as I'm very out-of-office -- #37394 has a similar error message, during which debug variable locations are implicated in an LTO / IRMover context. The story there is something to do with debug-info materializing something that doesn't have any "real" references, which feels like the kind of thing we might do by mistake with RemoveDIs.
