Please review this change in VS2017 to the delete operator due to C++14 
standard conformance.  From 
https://msdn.microsoft.com/en-us/library/mt723604.aspx

The function|void operator delete(void *, size_t)|was a placement delete 
operator corresponding to the placement new function "void * operator 
new(size_t, size_t)" in C++11. With C++14 sized deallocation, this 
delete function is now a/usual deallocation function/(global delete 
operator). The standard requires that if the use of a placement new 
looks up a corresponding delete function and finds a usual deallocation 
function, the program is ill-formed.

Thank you to Kim Barrett for proposing the fix below.
