[Bug c++/14369] New: errenous reject of well-formed code

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

Current mainline rejects the following (I think GCC-3.4.x is affected as
well but I did not check).

struct A { };

template<class T> 
struct X : A {
   const A* bar() const
   { return this; }

   const A& foo() const;
};

template<class T>
const A& X<T>::foo() const
{
   const A* t = bar();
   return *(t ? t : throw 0);
}


with the rather esoteric:
 
t.C: In member function `const A& X<T>::foo() const':
t.C:15: error: `#`throw_expr' not supported by dump_expr#<expression error>' has
type `void' and is not a throw-expression


The pretty-printing error is easily fixed, but that is not the main
point of the PR.  This is reject valid and a regression from at least
GCC-3.3.x
