--- Comment #2 from Tom Tromey <tromey at sourceware dot org> ---
The main question I have is why re-reading minimal symbols happens.
I guess this 'if' fails to trigger:

  if (objfile->per_bfd->minsyms_read
      && ei->stabsect =3D=3D NULL
      && ei->mdebugsect =3D=3D NULL
      && ei->ctfsect =3D=3D NULL)
    {
      if (symtab_create_debug)
        gdb_printf (gdb_stdlog,
                    "... minimal symbols previously read\n");
      return;
    }

... but for which reason exactly?

That would help make a reproducer, I guess.
You could probably trigger it by making a new inferior
and using 'file' to open the same ELF file again.
