The following code causes an ICE.  This code is certainly invalid as it stands, though it is derived from something larger which I think is valid.

namespace SArray {

class ColumnMajor;

template <typename T, int rank> class Array;

}

template <typename T, int rank>
void xxx(const SArray::Array<T, rank> & arr)
{
    SArray::Array<T, rank> arr_contiguous = arr;
    arr_contiguous.force_ordering<typename SArray::ColumnMajor>();
}


Here is the compiler output:
