            Bug ID: 61763
           Summary: [4.9 Regression] gcc-4.9.0 "Bootstrap comparison
                    failure!"
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dougmencken at gmail dot com

I tried to bootstrap gcc-4.9.0 release on OS X 10.5 (darwin9).
My host compiler is currently gcc-4.8.3.

That's what I've got:

gcc-4.8.3 bootstraps perfectly (both with -O2 and -O3) on my side.
