--- Additional Comments From pinskia at gcc dot gnu dot org 2005-07-26 13:11 --- Confirmed, one warning comes from the front-end and the other bogus warning comes from the middle-end. I have not looked to see if we set TREE_NO_WARNING on the return and if the middle-end looks at that flag but I think that might be a way around the issue. -- What|Removed |Added Status|UNCONFIRMED |NEW Ever Confirmed||1 Keywords||diagnostic Last reconfirmed|-00-00 00:00:00 |2005-07-26 13:11:36 date|| Summary|Redundant / bogus warning |[4.0/4.1 Regression] ||Redundant / bogus warning Target Milestone|--- |4.0.2 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23075
