[Bug c++/25768] [3.4 regression] wrong code with inlining at -O2

[pinskia at gcc dot gnu dot org]

------- Comment #5 from pinskia at gcc dot gnu dot org  2006-01-13 03:34 -------
You are violating C++ aliasing rules, you have:
int new_ybar_inline
          p = reinterpret_cast<void *>( free_list );
          free_list = free_list->next;
......
return p;

  *newchild = new_ybar_inline();
  (*newchild)->kind = interior;

so you are accessing the same memory location via two types.
