I've got this point, makes sense. But I don't get why is that related to --wide
option?
To be honest, the output of non-wide mode is longer and more verbose than
--wide option
output:

$ readelf --debug-dump=info --wide /tmp/sample_struct.o | head -n20 | grep
offset
    <11>   DW_AT_name        : (strp) (offset: 0x12d):
mpers-m32/sample_struct.c
    <15>   DW_AT_comp_dir    : (strp) (offset: 0x89):
/home/abuild/rpmbuild/BUILD/strace-5.10
    <20>   DW_AT_name        : (strp) (offset: 0x56): unsigned char

$ readelf --debug-dump=info /tmp/sample_struct.o | head -n20 | grep offset
    <11>   DW_AT_name        : (indirect string, offset: 0x12d):
mpers-m32/sample_struct.c
    <15>   DW_AT_comp_dir    : (indirect string, offset: 0x89):
/home/abuild/rpmbuild/BUILD/strace-5.10
    <20>   DW_AT_name        : (indirect string, offset: 0x56): unsigned char

...

I can report that to them. It's unpleasant that parsing would depend
on the version of binutils.

Thanks,
Martin
