We're running into this abort in process_psymtab_comp_unit: ... switch (reader.comp_unit_die->tag) { case DW_TAG_compile_unit: this_cu->unit_type = DW_UT_compile; break; case DW_TAG_partial_unit: this_cu->unit_type = DW_UT_partial; break; default: abort (); } ... because reader.comp_unit_die->tag == DW_TAG_type_unit. Fix this by adding a DW_TAG_type_unit case.
