--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> ---
we run into this abort:
...
(gdb) down
#2  0x000000000062ecba in process_psymtab_comp_unit (this_cu=3D0x20c0120,=20
    per_objfile=3D0x20612a0, want_partial_unit=3Dfalse,
pretend_language=3Dlanguage_minimal)
    at src/gdb/dwarf2/read.c:7837
7837          abort ();
...
because we don't handle:
...
(gdb) p reader.comp_unit_die->tag
$1 =3D DW_TAG_type_unit
...
in the switch:
...
  switch (reader.comp_unit_die->tag)
    {
    case DW_TAG_compile_unit:
      this_cu->unit_type =3D DW_UT_compile;
      break;
    case DW_TAG_partial_unit:
      this_cu->unit_type =3D DW_UT_partial;
      break;
    default:
      abort ();
    }
...
