[Bug middle-end/32856] Invalid optimization in the face of aliasing

[falk at debian dot org]

------- Comment #3 from falk at debian dot org  2007-07-22 23:01 -------
Can you give an example how n->next->next->prev and n->next might be at the
same address? I don't see any legal way to achieve that.

And FWIW, DEC C also optimizes like gcc does.
