           Summary: Segfault building newlib for bfin
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: shenders@gcc.gnu.org


building bfin with newlib-1.18 appears to have been broken on trunk since
r172258.  We get a seg fault when building newlib:
