MSVC documentation states: "This warning can be caused when a pointer to
a const or volatile item is assigned to a pointer not declared as
pointing to const or volatile."
Unfortunately, this happens when we dynamically allocate and deallocate
block of atomic variables using isc_mem_get and isc_mem_put.
Couple of examples:
