--- Comment #5 from Tom de Vries <vries at gcc dot gnu.org> ---
In terms of debug info, we're dealing with a forward inter-CU reference to =
an
abstract origin:
...
 <0><14b64e8>: Abbrev Number: 1 (DW_TAG_compile_unit)
  ...
 <1><14fc06f>: Abbrev Number: 45 (DW_TAG_variable)
    <14fc070>   DW_AT_abstract_origin: <0x5355817>
    <14fc074>   DW_AT_location    : (DW_OP_addr: 1fd8be8)
  ...
 <0><530411b>: Abbrev Number: 235 (DW_TAG_compile_unit)
  ...
 <1><5355817>: Abbrev Number: 95 (DW_TAG_variable)
    <5355818>   DW_AT_name        : all_bfds
    <535581c>   DW_AT_decl_file   : 186
    <535581d>   DW_AT_decl_line   : 58
    <535581e>   DW_AT_decl_column : 15
    <535581f>   DW_AT_type        : <0x5344aaa>
...

[ FWIW, the address used in the DW_AT_location attribute looks correct:
...
$ nm ./gdb-x | grep all_bfds
0000000001fd8be8 b _ZL8all_bfds
... ]
