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.
