aha, I missed that, sorry. But this comes back to my comment on the other patch. In the case of readelf.c this makes sense, since it uses libdwfl to access the elf data it can "transparently" read the compressed data. But other callers might not be able to process compressed sections. So I think we should carefully audit all callers to make sure that if debugscn_p () returns true for a compressed section then they are actually able to process the data.
