Hi,

#include <stdio.h>

struct B

  B()
  {
    printf("B::B() %08x\n", this);
  }

  ~B()
  {
    printf("B::~B() %08x\n", this);
  }
};

struct C
{
  C(const B &b)
  { }
};

B f()
{
  B b;
  return b;
}

int main()
{
  C c1 = f();
  // B::~B should be called here (just after C::C(const B &))

  C c2 = f();
  // B::~B should be called here (just after C::C(const B &))

  printf("done\n");

  return 0;
}

// but the output with 8.35.8n is:
// B::B() 0012ff7d
// B::B() 0012ff7f
// done
// B::~B() 0012ff7f
// B::~B() 0012ff7d


See 12.8 Copying class objects [class.copy], paragraph 15.
