When I compile this test case with gcc 4.1, 4.2, or mainline, I get an ICE:
foo.cc: In instantiation of Âconst unsigned char B<unsigned char>::cÂ:
foo.cc:20: instantiated from Âconst unsigned char C<A<unsigned char> >::cÂ
foo.cc:26: instantiated from here
foo.cc:20: internal compiler error: in instantiate_decl, at cp/pt.c:14162
As far as I can see this is valid C++ code.
template<typename T> class A
{
public:
typedef T T1;
};
template<typename T> class B
{
public:
static const T c;
};
template<unsigned char>
const unsigned char B<unsigned char>::c = 1;
template<typename T> class C
{
public:
typedef typename T::T1 T2;
static const T2 c = B<T2>::c;
};
unsigned char
fn ()
{
return C<A<unsigned char> >::c;
}
