             Bug #: 56301

           Summary: [4.7 Regression] wrong code with the fix for PR53844

    Classification: Unclassified

           Product: gcc

           Version: 4.7.3

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: middle-end

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: d...@gcc.gnu.org





works with 4.6 branch, 4.7.2 and the trunk. introduced in r195708 by the fix

for PR53844.



I don't have a reduced testcase yet. the unreduced test case is that the

upstart build in Ubuntu raring hangs in the testsuite with:



  Testing job_deserialise() ptrace handling

  BAD: wrong value for job->goal, expected 1 got 0

   at tests/test_job.c:7331 (deserialise_ptrace_next).



still trying to isolate the failure.



afaics, it is not architecture specific.



Even if backports are tested together, it would help if independent patches

could be committed separately to the branches.
