it
gdb.log (gdb.dwarf2/dw2-symtab-includes.exp)

Another one.

A data race between is_dwz in dwarf2_find_containing_comp_unit:
...
      if (mid_cu->is_dwz > offset_in_dwz
          || (mid_cu->is_dwz =3D=3D offset_in_dwz
              && mid_cu->sect_off + mid_cu->length > sect_off))
...
and again lang in prepare_one_comp_unit:
...
    cu->per_cu->lang =3D dwarf_lang_to_enum_language (attr->constant_value =
(0));
...

Not sure how to fix this yet.
