[Bug lto/43898] New: -flto -g: "tree check: expected class 'type', have 'declaration'"

["max at duempel dot org" <gcc-bugzilla at gcc dot gnu dot org>]

With "-flto -g", the following source will bail out with an internal compiler
error:

 void bug() {
   struct Class {
     Class(int a) {}
     virtual void f() {}
   };
   Class a(0);
 }

Command line: g++-4.5 -g -flto bug.cxx

Error message:

 bug.cxx: In member function 'bug()::Class::f()':
 bug.cxx:4:23: internal compiler error: tree check: expected class 'type', have
'declaration' (function_decl) in gen_type_die_with_usage, at dwarf2out.c:18962
