That's the early debug. The late debug is
<1><f4>: Abbrev Number: 2 (DW_TAG_imported_unit)
<f5> DW_AT_import : <0x135> [Abbrev Number: 1]
<1><f9>: Abbrev Number: 3 (DW_TAG_subprogram)
<fa> DW_AT_abstract_origin: <0x444>
<fe> DW_AT_low_pc : 0x4004e2
<106> DW_AT_high_pc : 0x41
<10e> DW_AT_frame_base : 1 byte block: 9c (DW_OP_call_frame_cfa)
<110> DW_AT_GNU_all_tail_call_sites: 1
<2><110>: Abbrev Number: 4 (DW_TAG_formal_parameter)

<2><128>: Abbrev Number: 0
<1><129>: Abbrev Number: 0
which indeed misses locations for the labels. I suppose late debug generation
somehow doesn't work for them. I will have a look.
