The following invalid code snippet triggers an ICE since GCC 4.1.2:

===============================
struct A
{
  template<int> void foo();
};

struct B : A {};
struct C : A {};

void bar()
{
  B().C::foo<0>();
}
===============================

bug.cc: In function 'void bar()':
bug.cc:11: internal compiler error: in build_base_path, at cp/class.c:272
Please submit a full bug report, [etc.]

Before GCC 3.4.0 we generated a correct diagnostic:
bug.cc:11: error: type `C' is not a base type for type `B'

GCC 3.4.0 - 4.1.1 wrongly accepted the code.
