The following invalid testcase triggers an ICE since GCC 4.0.0:
=========================================
struct A { virtual ~A(); };
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
