[libcxx-commits] [PATCH] D63050: Test that correct value category is used in scoped_allocator_adaptor::construct

[Zoe Carver via Phabricator via libcxx-commits]

zoecarver added a comment.

For the pair section of the issue, I ran into a few problems. The genesis of the problem is the fact that this compiles (and I can't figure out why):

  struct Foo
  {
  	typedef std::allocator<Foo> allocator_type;
  	
  	Foo(std::allocator_arg_t, allocator_type&&) { }
  	Foo(allocator_type&) { }
  };
  
  int main()
  {
  	using Alloc1 = std::allocator<pair<Foo, Foo>>;
  	using Alloc2 = std::allocator<Foo>;
  	static_assert( std::is_constructible<Foo, std::allocator_arg_t, Alloc1&>::value);
  	static_assert(!std::is_constructible<Foo, std::allocator_arg_t, Alloc2&>::value);
  }
