another testcase showing a similar bug:

#include <memory>

template<typename T>
struct Alloc : std::allocator<T>
{
    template<typename U> struct rebind { typedef Alloc<U> other; };

    template<typename U> Alloc(const Alloc<U>&) { }

    Alloc() = default;
    ~Alloc() noexcept(false) { }
};

Alloc<A> alloc;

auto x = std::allocate_shared<A>(alloc);
