           Version: 8.0
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: normal

          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

I will soon commit a patch that breaks (and xfails)
gcc.dg/Wstrict-overflow-18.c, see
https://gcc.gnu.org/ml/gcc-patches/2017-04/msg00986.html. As asked by Martin,
this PR is here to track this regression.

Most likely this will be solved by Richard (or someone else) killing
-Wstrict-overflow.
