There is a gcc 2.95.3 compiler bug where inheriting from a base class with a
private 'operator delete' (and its matching partner 'operator new') complains
and bails. Privitizing class specific operator new/delete pair is a common idom
to prevent freestore allocation. This is fixed in later version of gcc.
1 #include <sys/types.h>
2
3 class Base
4 {
5 public:
6 Base() {}
7 ~Base() {}
8 private:
9 // Prevent allocation on freestore -- privitize op new/delete
10 static void* operator new (size_t size);
11 static void operator delete(void*);
12 };
13
14 class Derived : public Base
15 {
16 public:
17 Derived() {}
18 ~Derived() {}
19 };
% gcc -save-temps -Wall baseopdelete.cpp
baseopdelete.cpp: In method `Derived::~Derived()':
baseopdelete.cpp:11: `static void Base::operator delete(void *)' is private
baseopdelete.cpp:18: within this context
