I agree.  This change would make gdb's behavior less surprising in some
corner cases, and I think it is hard to argue that people know or rely
on gdb's current behavior.

Yes, I think you'd need this change there as well.

gdb should end up in the lookup_symbol_aux_quick loop if the symbol in
question is in an unexpanded psymtab.  In this case you want to be sure
to check the block objfile first.

Works for me.
