------- Comment #8 from rguenth at gcc dot gnu dot org 2010-02-15 14:53 -------
The issue _seems_ to be that the indirect assignment
;; *this.24_34 = __bound_args#0;
is from
;; Function std::_Head_base<_Idx, _Head, true>::_Head_base(_UHead&&) [with
_UHead = Inc, long unsigned int _Idx = 0ul, _Head = Inc] (null)
;; enabled by -tree-original
{
<<cleanup_point <<< Unknown tree: expr_stmt
(void) (*(struct Inc *) this = *(const struct Inc &) (const struct Inc *)
std::forward<Inc> ((struct type &) (struct Inc *) __h)) >>>
>>;
}
where we do not see its zero-sizeness(?) and thus end up not removing the
zero-sized assignment during cp_genericize_r.
Bah, because it's an INIT_EXPR, not a MODIFY_EXPR.
I have a patch.
