Public operator new, private operator delete: getting C2248 “can not access private member” when using new

Question

A class has overloaded operators new and delete. new is public, delete is private.

When constructing an instance

Answer 1

Calling operator new on class will use also delete class if class constructor throws an exception.

If your library does not use exceptions, you can disable exceptions from compiler "-fno-exceptions", then error won't appear anymore. (In Visual studio resides under "C/C++", "Code Generation", "Enable C++ Exceptions" > "No (-fno-exceptions)")
