I get errors before the ICE:
../src/typelist.hpp:49: error: 'uint' has not been declared

But after fixing the errors, I still get the ICE so reducing.

------- Comment #5 from pcarlini at suse dot de  2007-09-08 02:22 -------
Now the ICE is at line 6586. Can be triggered with this smaller snippet:

struct null_type;

template<typename T1, typename T2>
struct tuple_impl
{
  template<typename U>
  struct append
  {
    typedef tuple_impl<U, null_type> type;
  };

  int data;
};

template<typename T1, typename T2>
class tuple
: public tuple_impl<T1, null_type>::template append<T1>::type
{
  using tuple_impl<T1, null_type>::template append<T1>::type::data;
};

tuple<int, int>  my_tuple;

---------

Note that if I remove the now redundant template parameter T2 of tuple and
instantiate with typle<int>, we get immediately a bit of additional info:

33239_p2.C: In instantiation of ‘tuple<int>’:
33239_p2.C:22:   instantiated from here
33239_p2.C:19: internal compiler error: tree check: accessed elt 2 of tree_vec
