            Bug ID: 58368
           Summary: [4.9 regression] bootstrap comparison failure in
                    expr.o and i386.o on x86_64-linux
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mikpe at it dot uu.se

Attempting to bootstrap gcc-4.9-20130908 (r202372) on x86_64-linux fails with:

make[3]: Leaving directory `/mnt/scratch/objdir49'
Comparing stages 2 and 3

Applying r202379 didn't fix the comparison failure, but reverting r202345 did.
