Thanks for the investigation. Then I think that my latest patch
awaiting approval should fix this, if we're lucky - it treats C++
class symbols as global objects instead of static objects.
(Basically, we want to find the class before we ever reach the calls
to lookup_symbol_aux_{,p}symtabs in lookup_symbol_aux: it should be
found in the language-specific bit.) I'll double check to make sure
that's the issue, but I'm optimistic.
