            Bug ID: 80379
           Summary: Redundant  note: code may be misoptimized unless
                    -fno-strict-aliasing is used
           Product: gcc
           Version: 6.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: andi-gcc at firstfloor dot org
  Target Milestone: ---

I get an extra

 note: code may be misoptimized unless -fno-strict-aliasing is used

note for type mismatches in LTO builds. But -fno-strict-aliasing is already
set. In this case the extra note is pointless and should be suppressed.
