> Or are you talking only about the case of missing debug info?

Yes.  For example, if libc has no debug info then printf (which is a
symbol in the .opd section) resolves to the function descriptor address,
and to get the real code address you need to use '._IO_printf'.  The
ppc64 target is pretty unique in this behaviour, on ia64 you don't have
this problem even though it uses function descriptors as well.
