<pre>The following presumably valid C++14 code:
template <typename T>
struct Foo {
template <typename>
static constexpr auto v = 0;
static constexpr int w = v<T>;
};
template struct Foo<void>;
produces the following error:
error: cannot initialize a variable of type 'const int' with an lvalue of
type 'const auto'
static constexpr int w = v<T>;
^ ~~~~
Replacing 'auto' with 'decltype(0)' makes it compile.
Versions 8 and below work fine. Versions 9 and 10 produce the error. GCC
works fine too.</pre>
