I've filed a DWARF issue to reserve "-1" as the tombstone address value. I wrote it up such that consumers should ignore that address and any address derived from it (e.g., base+offset). I don't have the issue number for it yet, hopefully I'll remember to post it here when it's assigned.
Using -2 for .debug_loc/.debug_ranges would have to be a convention, but is entirely "legal" from a DWARF standards perspective.
