<div>
<pre>clang fails the following static assertion
template<typename, typename>
struct foo {};
struct bar : foo<void, int>, foo<void, int*> {};
template<typename T>
T f(foo<void, T>&&);
void f(...);
static_assert(std::is_same<decltype(f(std::declval<bar>())), void>{}, "");
it turns out clang chooses the first overload of f and incorrectly deduces T to
be int*</pre>
