A solution would be to wrap the placement in a SAVE_EXPR in all callers of
avoid_placement_new_aliasing, thus the following seems to fix it:
Index: init.c
===================================================================
*** init.c (revision 141164)
--- init.c (working copy)
*************** build_new_1 (tree placement, tree type,
*** 2041,2046 ****
--- 2041,2047 ----
|| VOID_TYPE_P (TREE_TYPE (TREE_TYPE (placement_arg))))
{
placement_expr = get_target_expr (TREE_VALUE (placement));
+ placement_expr = save_expr (placement_expr);
CALL_EXPR_ARG (alloc_call, 1)
= convert (TREE_TYPE (placement_arg), placement_expr);
}
