No problem.

What is odd is that my 7.2 does exactly what my later builds do.
Does your build have local patches that might affect this?
Could you possibly try 7.3.1 or CVS HEAD?
Otherwise I am wondering whether it is somehow a compiler difference.

The same:

(gdb) p *(class Apple *) this
$5 = (Fruit) {
  _vptr.Fruit = 0x400910, 
  fruit1 = 1, 
  fruit2 = 2, 
  fruit3 = 3, 
  fruit4 = 4
}

I tend to agree with you that gdb should show an Apple here, not a Fruit.
