We can easy see the problem on the mainline by looking at the tree dumps:
  [pr18098.cc : 31] D.1709 = [pr18098.cc : 31] top (this);
  [pr18098.cc : 31] D.1707 = D.1709;
  [pr18098.cc : 31] D.1710 = D.1707;
  [pr18098.cc : 31] D.1711 = (int (*__vtbl_ptr_type) (void) * *) D.1710;
  [pr18098.cc : 31] D.1712 = *D.1711;


Note how we dereference D.1711 but this is also the return value from top where 
the problem comes 
from.
