[Bug debug/22583] New: polymorphic local class => ICE in in lookup_decl_die, at dwarf2out.c:5461

[Bug debug/22583] New: polymorphic local class => ICE in in lookup_decl_die, at dwarf2out.c:5461

[gdr at gcc dot gnu dot org]

GCC mainline is now ICEing on the following snipped 
(reduced from real-world code)

   struct A {
      virtual ~A() { }
   };

   void f()
   {
      struct B : A {
      };

      B b;
   }

Use g++ -g.

My preliminary analysis indicates that the ICE occurs while
building the vtable for the local class f::B.  

I believe this to be related to Dan's recent rework.

For some reasons Bugzilla did not want to understand that I'm reporting the
bug agains 4.1.0.

Actually it is only related to virtual function in a local class.  And this is a dup of bug 22034 and has 
nothing to do with Dan's rewrite at all but Honza's patch: <http://gcc.gnu.org/ml/gcc-cvs/2005-06/
msg00388.html>.

*** This bug has been marked as a duplicate of 22034 ***

Great!  

Apologies to Dan.
