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
