Sie troche pomyliłem... Powinno być tak:

#include <iostream>
#include <memory>
using namespace std;
char tab[100];
struct Bar{
Bar(){cout <<"Bar"<<endl;}
~Bar(){cout <<"~Bar"<<endl;}
};
class Foo{
std::auto_ptr<Bar> b;
public:
Foo() : b(new Bar())
{
cout <<"Foo"<<endl;
throw 1;
}
~Foo()
{
cout <<"~Foo"<<endl;
}
static void * operator new (size_t size)
{
cout <<"new"<<endl;
return (Foo*)tab;
}
static void operator delete (void *p, size_t size)
{
cout <<"delete"<<endl;
}
};

main()
{
try{
Foo *f=new Foo();
}
catch(...){
cout <<"catch"<<endl;
}
}
