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

The following is invalid C++ and should be rejected:
struct Thing {
  Thing(){}
};

int f (int i)
{
  switch (i)
  {
  case 1:
    Thing *str = new Thing;
  case 2:
  case 3:
    ;
  }
  return 0;
}

Previous versions before 4.0.0 rejected with the following message:
t.cc:11: error: jump to case label
t.cc:10: error:   crosses initialization of `Thing*str'
t.cc:12: error: jump to case label
