Short C++ program to demonstrate the bug

A bug was introduced so that a return such as 
  Link & n = f->*Ptr;
  return n.next;
generates an incorrect warning about a stack address being returned.

I bisected this problem to

commit 354438d88cbb857858ffcbde72d4723b8548ce0a

    Fold -Wreturn-stack-address into general initialization lifetime
    checking.
