[Bug c++/38638] New: [4.2/4.3/4.4 regression] ICE superfluous 'typename'

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE since GCC 4.2.0:

========================================
struct A
{
  template<int> void foo(int i)
  {
    typename A::foo<0>(i);
  }
};
========================================

bug.cc: In member function 'void A::foo(int)':
bug.cc:5: internal compiler error: in start_decl, at cp/decl.c:4189
Please submit a full bug report, [etc.]

The code was wrongly accepted by GCC 3.4.x, 4.0.x, and 4.1.x.
It was correctly rejected by GCC 3.3.6 and earlier.
