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

The following invalid code snippet triggers an ICE since GCC 3.0:

=================================================
template<typename T> void foo(T)
{
  struct A
  {
    template<int> struct B
    {
      typedef B<0> C;
    };
  };
}
=================================================

bug.cc: In function 'void foo(T)':
bug.cc:1: internal compiler error: in tsubst, at cp/pt.c:7337
Please submit a full bug report, [etc.]
