           Summary: FSF gcc 4.6.1 fails to bootstrap on Core Solo/Core Duo
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal

        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: howarth@nitro.med.uc.edu


The bootstrap of FSF gcc 4.6.1 fails on Core Solo/Core Duo processors when
configure is executed within the x86_64 multilib and attempts to execute x86_64
code on a non-EMT64 processor. This failure in the config.log from the x86_64
multilib of libquadmath is...
