>Description:
I found this on gcc-2.95.2 but it's still present on the
CodeSourcery version.
>How-To-Repeat:
cat > foo.cc << EOF
class A {
    private:
        void operator delete(void*);
    public:
        virtual ~A() { }
};

class B : public A {
    public:
        virtual ~B() { }
};
EOF
gcc -c foo.cc
>Fix:
Make delete be accessible to B (protected, for instance).
Never destroy a B.
