objdump -dCrS also prints these errors.
It definitely fails to find the entry for main which is present according to
objdump --dwarf:
<1><dc>: Abbrev Number: 8 (DW_TAG_subprogram)
<dd> DW_AT_external : 1
<dd> DW_AT_name : (indirect string, offset: 0x1ab): main
<e1> DW_AT_decl_file : 1
<e2> DW_AT_decl_line : 8
<e3> DW_AT_decl_column : 5
<e4> DW_AT_type : <0xc3>
