            Bug ID: 79293
           Summary: [7 regression] gcc.dg/tree-ssa/builtin-sprintf.c fails
                    starting with r244953
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: seurer at gcc dot gnu.org
  Target Milestone: ---

At least I think it is 244753.  There were a bunch of updates for that revision
which left the compiler unable to build but after those were cleared up
builtin-sprintf was failing.
