struct B : A A {};

A foo(const B &b)
{
  return b;
}
=========================================

bug.cc:3: error: expected `{' before 'A'
bug.cc:3: error: function definition does not declare parameters
bug.cc: In function 'A foo(const B&)':
bug.cc:7: internal compiler error: in build_simple_base_path, at cp/class.c:475
