  Target Milestone: ---

I am currently porting sqlpp11 to C++17 and encountered a compiler crash using
the following code

// -------------------------------
template <const char& V>
using char_sequence_t = int;

template <typename T>
constexpr char name_of_v = 'x';

template <typename T>
using type = char_sequence_t<name_of_v<T>>;
// -------------------------------
