That says the duplicate CIE has been dropped, but not the FDE for the discarded
section.  (Hmm, check that the map file lists the discarded sections from
test2.o comdat groups)

Whereas here both the CIE and FDE have been dropped, as they should be.

The decision to drop FDEs is made in elf_eh_frame.c line 1175:
    keep = !(*reloc_symbol_deleted_p) (ent->offset + 8, cookie);
