C++14 3.7.4.2/p2 says "If a class T has a member deallocation function named operator delete with exactly one parameter, then that function is a usual deallocation function. If class T does not declare such an operator delete but does declare a member deallocation function named operator delete with exactly two parameters, the second of which has type std::size_t, then this function is a usual deallocation function." We're running into problems because we have a placement new with an apparently corresponding usual delete. One possibility is to make that two-argument delete a placement deallocation function, rather than a usual deallocation function. I think we can accomplish that by just adding a one-argument delete.

VS2017 description and a suggested fix can be found at: https://msdn.microsoft.com/en-us/library/mt723604.aspx, search for "Placement new and delete". Removing Chunk::operator delete in order to force the compiler to prefer the new global placement delete operator does not resolve the issue.
