[Bug c++/28742] New: [4.2 regression] ICE with virtual destructor in invalid template class

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

The following invalid testcase triggers an ICE on mainline:

=========================================
template<void> struct A
{
  A();
  virtual ~A();
};

A<0> a;
=========================================

bug.cc:1: error: 'void' is not a valid type for a template constant parameter
bug.cc:3: error: templates may not be 'virtual'
bug.cc: In instantiation of 'A<<expression error> >':
bug.cc:7:   instantiated from here
bug.cc:3: internal compiler error: in finish_member_declaration, at
cp/semantics.c:2243
Please submit a full bug report, [etc.]

If I remove the constructor or destructor, the ICE happens in the same
place as PR 24791.

This is probably fallout from PR 27668.
