--- Comment #3 from Jonathan Wakely ---
Or this version is valid C++11 (and accepted by clang and EDG):
template
struct array
{
T _M_data[N];
};
template
struct integer_sequence
{
};
struct Pos
{
unsigned l;
};
template
constexpr array make_grid_position(integer_sequence)
{
return {{ Pos{Ints}... }};
}
constexpr array make_grid_positions()
{
return make_grid_position(integer_sequence{});
}
template
void generate_sudoku(T)
{
constexpr auto positions = make_grid_positions(); // fail
}
int main()
{
constexpr auto positions = make_grid_positions(); // ok
generate_sudoku(1);
}

Preprocessing with 4.9.3 and compiling with trunk fails, so it's a front-end regression (not something in the library). I'll try to reduce it.
