--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> 2011-08-31 21:03:36 UTC --- >GCC 4.6.0 20110603 (Red Hat 4.6.0-10)). Does it happen with non RedHat version of the compiler meaning non modified version of GCC? Really you should have reported this first to redhat as they have some modifications to their compiler that might have caused this issue.
