Re: debug/8095: missing dwarf info for parent class

Sorry, I understood this but just wanted to raise the issue again -- 
opinions will not come in if the question bitrots in gnats :-) (Which is 
not your fault -- you had asked, but received no answers.)

This doesn't strike me as a particularly useful idea, since then you would 
have to emit debug info in every compilation unit that includes a certain 
header file. This might be a lot of duplication.

If there are ways to tie debug output to a certain member of a class (just
as we do for vtables), then I would say this is a good idea. If someone
doesn't like this, then compile your library with -g.

But that's just my opinion.
