Re: Is it *legal* (as opposed to sensible) to explicitly destruct an object and deallocate the memory?

The following might be a consideration:

struct foo
{
foo()
{
std::cout << "foo ctor called\n";
}
~foo()
{
std::cout << "foo dtor called\n";
}
void* operator new(std::size_t aSize)
{
std::cout << "overloaded operator new called\n";
return ::operator new(aSize);
}
void operator delete(void* p)
{
std::cout << "overloaded operator delete called\n";
return ::operator delete(p);
}
};

int main()
{
foo *x = new foo;
delete x;
//x->~foo();
//::operator delete(x);

foo *y = new foo;
//delete y;
y->~foo();
::operator delete(y);

return 0;
}

outputs:

overloaded operator new called
foo ctor called
foo dtor called
overloaded operator delete called
overloaded operator new called
foo ctor called
foo dtor called
