I think it is a linker dwarf reader problem. Gcc may generate:

         .section .gnu.linkonce.wi.client.cpp.7682538d,"",@progbits
         ...
DW.client.cpp.7682538d.2b:
        .uleb128 0xd
        .long   0x16a
        .byte   0x1
        .long   .LASF10
        .byte   0x1
        .byte   0x25
        .byte   0x1
        .uleb128 0xe
        .long   0x114
        .byte   0x1
        .byte   0x0


        .section        .debug_info
        ...
        .uleb128 0x8d
        .long   0x1c3f
        .quad   DW.client.cpp.7682538d.2b
        .byte   0x0

When reporting linker error, dwarf2 reader assumes that there is only
one .debug_info section. DW_FORM_ref_addr reference to
DW.client.cpp.7682538d.2b isn't handled properly.
