--- Comment #17 from Richard Biener <rguenth at gcc dot gnu.org> ---
Re-confirmed.  The gimplifier sees

(gdb) p debug_tree (*expr_p)
 <offset_ref 0x7ffff64320a0
    type <method_type 0x7ffff642a498
        type <void_type 0x7ffff6289f18 void type_6 VOID
...
(gdb) p debug_generic_expr (*expr_p)
<<< Unknown tree: offset_ref
  **a0
  *f >>>

which supposedly is not to survive this long.
