bfd/elf.c:

static bfd_boolean
swap_out_syms (bfd *abfd,
               struct bfd_strtab_hash **sttp,
               int relocatable_p) {
...
                  /* Writing this would be a hell of a lot easier if
                     we had some decent documentation on bfd, and
                     knew what to expect of the library, and what to
                     demand of applications.  For example, it
                     appears that `objcopy' might not set the
                     section of a symbol to be a section that is
                     actually in the output file.  */
fprintf(stderr, "vda: sec->name '%s'\n", sec->name);
                  sec2 = bfd_get_section_by_name (abfd, sec->name);
                  if (sec2 == NULL)
                    {
                      _bfd_error_handler (_("\
Unable to find equivalent output section for symbol '%s' from section '%s'"),
                                          syms[idx]->name ? syms[idx]->name :
"<Local sym>",
                                          sec->name);
                      bfd_set_error (bfd_error_invalid_operation);
                      _bfd_stringtab_free (stt);
                      return FALSE;
                    }

fprintf(stderr, "vda: sec2->name '%s'\n", sec2->name);
                  shndx = _bfd_elf_section_from_bfd_section (abfd, sec2);
                  BFD_ASSERT (shndx != -1);

Both print the same:

vda: sec->name '*GAS `reg' section*'
vda: sec2->name '*GAS `reg' section*'

This section is created here: gas/as.c:

static void perform_an_assembly_pass (int argc, char ** argv) {
...
  reg_section = subseg_new ("*GAS `reg' section*", 0);

and is removed in gas/write.c:

void write_object_file (void) {
...
    bfd_section_list_remove (stdoutput, reg_section);


write_object_file() is invoked in main() way before xexit() ->
-> bfd_close()
-> BFD_SEND_FMT (abfd, _bfd_write_contents, (abfd)))
-> _bfd_elf_write_object_contents
-> _bfd_elf_compute_section_file_positions
-> swap_out_syms
